Answer / n. vijaya lakshmi
Answer - 17
Solution -
8 + 11 = 19
19 + 2 = 21
21 + 4 = 25
25 + (-5) = 20
20 +/- ? = ?
Now, the real question is 11, 2, 4, -5, ?
11 - 7 = 4
2 - 7 = -5
That's how we got, 11,2,4 and -5.
Now, 4 - 7 = (-3)
subtracting -3 from 20, we get 17.

-9 2 -9 x3
Here x3 should be 2 bcoz the sequence is -9, 2, -9, 2,...
thus x2 = -5 + 2 = -3
and hence x1 = 20 + (-3) = 17
thus the answer 17.
