Question

(9/13×-11/17) ^-6 =13/9^6×(17/11) ^6
​

Answer 1

Answer:

square of odd numbers starting from one. So our answer will be 9^2 = 81.

Let us look at another example:

1 , 1 , 2 , 4 , 3 , 9 , 4 , ?

We observe here that the series is formed by writing numbers starting from 1 along with its square as the next number i.e. ( 1 , 12) , (2, 22) and so on. So we obtain our answer as 16 which is 42.

Consider the following question:

9 , 28 , ? , 126.

The answer for above question will be 65, let us discuss how.

9         ,                 28   ,     ?     ,    126.

( 23+1)   (33+1)                 (53+1)

The blank should have 43+1. Hence, the answer is 65.
