Look at the series
8,43,11,41,____,39,17.
What number should fill in the blank?
Read Solution (Total 68)
-
- 14,two series are combined.8,11,_,17 are of one series and 43,41,39 are another series.the possible number which formed by increasing 3 to the previous number is 14
- 8 years agoHelpfull: Yes(19) No(1)
- 8+3=11,11+3=14,14+3=17
39+2=41,41+2=43 - 8 years agoHelpfull: Yes(7) No(0)
- in this above series we have 2 series
1st series 8,11,14,17...
increased each term by +3
2nd series 43,41,39,37....
decreased each term by -2
so,ans is 14 - 8 years agoHelpfull: Yes(3) No(0)
- Answer: Option B
Explanation:
This is a simple alternating addition and subtraction series. The first series begins with 8 and adds 3; the second begins with 43 and subtracts 2. - 8 years agoHelpfull: Yes(2) No(0)
- 14
this is a multiple series.Here 8+3=11
hence 11+3=14 - 8 years agoHelpfull: Yes(1) No(0)
- ans is 14
every time the numbers are being added and substracted consecutively.
each number being added and substracted is being decremented by 5 respectively.
8+35=43
43-32=11
11+30=41
41-27=14
14+25=39
39-22=17 - 8 years agoHelpfull: Yes(1) No(0)
- two series
1. 8 11 ? 17
2. 43 41 39
so missing number is 11+3=14
- 8 years agoHelpfull: Yes(1) No(0)
- 8+3=11
11+3=14 - 8 years agoHelpfull: Yes(1) No(0)
- 14
1 st number +3 is third number 3 rd number +3 is the fifth number
8,43,11,41,14,39,17
- 8 years agoHelpfull: Yes(1) No(0)
- 8+3=11
11+3=14
14+3=17
hence answer is 14 - 8 years agoHelpfull: Yes(1) No(0)
- ans is 14 because aternate terms are added by 3
- 8 years agoHelpfull: Yes(1) No(0)
- 14 between odd places numbers has difference of 3 and even place numbers has difference of -2
- 5 years agoHelpfull: Yes(1) No(0)
- difference between 8 and 11 is 3, difference between 43,41 is -2,same rule for next series so answer is 14
- 5 years agoHelpfull: Yes(1) No(0)
- odd places are increasing by 3 and even places are decreasing by 2
so the answer is "14" - 5 years agoHelpfull: Yes(1) No(0)
- here is a sequence 8,11 there is difference of 3 between them so next is 14
- 8 years agoHelpfull: Yes(0) No(0)
- here we can see the sequence 8+3=11
11+3=14 (ans)
14+3=17
and another side we also can see 43-2=41
41-2=39 - 8 years agoHelpfull: Yes(0) No(0)
- 8+3=11
43-2=41
11+3=14(answer)
41-2=39
14+3=17. - 8 years agoHelpfull: Yes(0) No(0)
- 14
1st term=8. so add 3 i.e 8+3=11(3rd term)
2nd term=43. so sub 2 i.e 43-2=41(4th term) - 8 years agoHelpfull: Yes(0) No(0)
- Alternate numbers in series have a constant difference i.e.
43-41 = 41-39 = 2
11-8 = 14-11 = 17-14 = 3
Hence the gap is satisfied by number 14. - 8 years agoHelpfull: Yes(0) No(0)
- 14
eight plus three is eleven,so eleven plus three is 14. - 8 years agoHelpfull: Yes(0) No(0)
- ans.14
8+3=11
11+3=14
14+3=17 - 8 years agoHelpfull: Yes(0) No(1)
- consider the series 8,11,14,17. it is like add 3 to the previous number...so the Ans is 14.
- 8 years agoHelpfull: Yes(0) No(0)
- 14 is the answer
- 8 years agoHelpfull: Yes(0) No(0)
- 14 is the answer
- 8 years agoHelpfull: Yes(0) No(0)
- 8 is one series and 43 is another series
8 values increasing by 3
43 decreased by 2
so,the missing number is 14. - 8 years agoHelpfull: Yes(0) No(0)
- answer is 14,why bcz while abserving the series we can notice that two types of series are their those are 8,11,14...... and 43,41,39..........
- 8 years agoHelpfull: Yes(0) No(0)
- This series is a combination of two series..first one is:
8+3=11
11+3=14
14+3=17
And the second one is:
43-2=41
41-2=39 - 8 years agoHelpfull: Yes(0) No(0)
- 14, the difference between 8 to 11 is 3 and
the difference between 43 to 41 is 2 and the difference between 41 to 39 also 2
So the series will be continuous, the number will be 14 with difference of 3 from 11 - 8 years agoHelpfull: Yes(0) No(0)
- 8+2=11
11+2=14
14+2=17
so answer is 14 - 8 years agoHelpfull: Yes(0) No(0)
- take 8,11,_,17 the difference is 3 so next no is 14
ans is 14 - 8 years agoHelpfull: Yes(0) No(0)
- Here , the difference between every odd position numbers is 3.
ex - 11 - 8 = 3
and the difference between every even position numbers i s2.
ex - 43 - 41 =2, 41 - 39 = 2,
so, the next number after 41 will be 11 + 3 = 14 , and thus 17 - 3 =14 .
so, ans = 14. - 8 years agoHelpfull: Yes(0) No(0)
- 14..
Because it's two consecutive series.. series of 8,11,14,17 wd 3 added each time - 8 years agoHelpfull: Yes(0) No(0)
- 14
1st 3rd so on position' s number is increasing by 3 - 8 years agoHelpfull: Yes(0) No(0)
- Here we can observe two series
1)8-11=3 ,11-x=?, here the common difference is 3 so that we can say next number should be 14
11-14=3 and 17-14=3.
2)43-41=2,41-39=2
- 8 years agoHelpfull: Yes(0) No(0)
- 14
8+3=11
then next
11+3=14 - 8 years agoHelpfull: Yes(0) No(0)
- 14 is the solution
As difference with simultaneously 3 and 2 - 8 years agoHelpfull: Yes(0) No(0)
- ans 14, because
to get second one we add 35 to the first one,
to get third one we subtract 32 from the second one,like the same way to get 5 th term in series we subtract 27 from the fourth term. - 8 years agoHelpfull: Yes(0) No(0)
- 14
add 3 with each odd terms - 8 years agoHelpfull: Yes(0) No(0)
- 14
add 2 to alternate numbers
- 8 years agoHelpfull: Yes(0) No(0)
- Ans: 14
It is combination of two series
1st series: 8,_,11,_,14,_17
2nd: _,43, _, 41,_,39 - 8 years agoHelpfull: Yes(0) No(0)
- 14.. two series are going on.. one is 8,11,14,17
and other is 43,41,39...
- 8 years agoHelpfull: Yes(0) No(0)
- 8,43,11,41,17,39,17........
- 8 years agoHelpfull: Yes(0) No(0)
- 8+3=11
43-2=41
11+3=14 ans
41-2=39
14+3=17
- 8 years agoHelpfull: Yes(0) No(0)
- The difference between the odd position in the series is 3
so 8,11,14,17
answer is 14 - 8 years agoHelpfull: Yes(0) No(0)
- 8.11.14.17
- 8 years agoHelpfull: Yes(0) No(0)
- break series in odd and even values
(8,11,x,17),(43,41,39)
we can see in odd terms, there is a addition of 3 and in even places, there is the diff of 2. thus x=11+3=14 - 8 years agoHelpfull: Yes(0) No(0)
- There is a increase of 3 in the odd places so,the 5th term is 14 and there is a difference of 2 in the even places like 43-41=2,41-39=2. so, the missing term is 14.
- 8 years agoHelpfull: Yes(0) No(0)
- ans is 14
8+3=11, 11+3=14, 14+3=17
alternative series - 8 years agoHelpfull: Yes(0) No(0)
- 8+3=11

- 14 alternatively increase +3
- 8 years agoHelpfull: Yes(0) No(0)
- 14
two series are there
8,11,____,17 (+3)
43,41,39(-2) - 8 years agoHelpfull: Yes(0) No(0)
- ANS.14
since the pattern goes like
8+3=11
43-2=41
41-2=39
therefore, 11+3=14 and 14+3=17 - 8 years agoHelpfull: Yes(0) No(0)

- mixture of two series
adding three to previous number will get one series and subtracting two from previous number will get second series
first series-8,11,14,17(8+3=11,11+3=14,14+3=17)
second series--43,41,39(43-2=41,41-2=39)
