Q. What is the next number of the following sequence.
11,17,-6,-13,24,30,-19,-26,20,....?
Read Solution (Total 14)
-
- difrnc b/w 11 nd 17 =6 and (-6,-13)=7
same way 30-24=6 and (-19,-26)=7
then 20-26=6
so ans is 26 - 11 years agoHelpfull: Yes(19) No(1)
- 17-11=6
-13+6=-7
30-24=6
-26+19=-7
x-20=6
so put the vale x=26
so (26-20)=6
so ans is 26 - 11 years agoHelpfull: Yes(8) No(1)
- (11,17)-> diff(17-11)=6
(-6,-13)-> diff(-13-(-6))=-7
(24,30)-> diff(30-24)=6
(-19,-26)-> diff(-26-(-19))=-7
(20,x)->diff(x-20)=6
so x is 26 and ans is 26

- 20+6=26 is the answer
- 11 years agoHelpfull: Yes(1) No(0)
- 11+6=17
(-6)+(-7)=-13
24+6=30
(-19)+(-7)=-26
20+6=26 - 11 years agoHelpfull: Yes(1) No(0)
- 26.. if we see all the positive no's , the difference among them is 6.. leaving the -ve no's considering them as garbage values.. the answer will be 20+6=26

- 11+6=17
(-6)-7=-13
24+6=30
(-19)-7=-26
20+6=26
so ans is 26 - 11 years agoHelpfull: Yes(1) No(0)
- Given 11,17,-6,-13,24,30,-19,-26,20 ?
Sum of positive numbers=11+17+24+30+20=102
Sum of negative numbers=-6-13-19-26=64
So I guess to compensate for positve terms next term should be -38 so that total sum would be zero and balanced. - 11 years agoHelpfull: Yes(0) No(2)
- ans 6
17-11=6
30-24=6
20-26=6
we do not need negative numbers
But relationship is 11+2=13(don't consider negative sign)
24+2=26(don't consider negative sign)
6+11=17
19+11=30 - 11 years agoHelpfull: Yes(0) No(3)
- 26,-15,-22 if you ask to continue that series, however if only one term is to be filled then 26 is correct answer. 11+13=24
17+13=30
24-4=20
30-4=26
similarly for negative numbers
-6 -13= -19
-13 -13= -26
-19+4=-15
-26+4=-22 - 11 years agoHelpfull: Yes(0) No(0)
- ans is 26....
- 11 years agoHelpfull: Yes(0) No(0)
- 11+6=17
-6-7=-13
24+6=30
-19-7=-26
20+6=26 here answer is 26

- wrong question shud be 11,17,-6,-13,24,30,-19,-26,? nd next ans is 37
- 8 years agoHelpfull: Yes(0) No(0)
- Consider the series:11,17,-6,-13,24,30,-19,-26
All other Answers are wrong.
The correct ans is:37
The difference b/w 11 and 17 is: 6 and the difference b/w -6 and -13 is 7. add 17+7=24
The difference b/w 24 and 30 is: 6 and the difference b/w -19 and -26 is 7. add 30+7=37 - 6 years agoHelpfull: Yes(0) No(0)
