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

akhilesh kumar  (10 years ago)

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

vinoth  (10 years ago)

(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

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

mohammad sabir hossain  (10 years ago)

11+6=17
(-6)-7=-13
24+6=30
(-19)-7=-26
20+6=26
so ans is 26

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.

Praveen Kumar  (10 years ago)

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

Sonu Kumar Sharma  (10 years ago)

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

Arunkumar K  (5 years ago)

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
