anupama  (7 years ago)

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

14
this is a multiple series.Here 8+3=11
hence 11+3=14

Is this solution Helpfull? Yes (1) | No   

Aman Saxena  (7 years ago)

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

2nd term=43. so sub 2 i.e 43-2=41(4th term)

Is this solution Helpfull? Yes | No   

sachin soni  (7 years ago)

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.

lakshmi lavanya naru  (7 years ago)

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

Is this solution Helpfull? Yes | No   

priya goel  (7 years ago)

take 8,11,_,17 the difference is 3 so next no is 14
ans is 14

Is this solution Helpfull? Yes | No   

Richa Pandey  (7 years ago)

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.

Is this solution Helpfull? Yes | No
