17. 

Which one will replace the question mark ?

[A]. 64
[B]. 144
[C]. 169
[D]. 25

Answer: Option A

Explanation:

The numbers are squared in ascending order

In first circle,

(3)2 = 9

(4)2 = 16

(5)2 = 25

(6)2 = 36.

In second circle,

(4)2 = 16

(5)2 = 25

(6)2 = 36

(7)2 = 49.

In third circle,

(6)2 = 36

(7)2 = 49

(8)2 = 64

(9)2 = 81.

Another process

36 - 16 + 9 = 29 - 4 = 25.
49 - 25 + 16 = 40 - 4 = 36.
81 - 49 + 36 = 68 - 4 = 64.

So the answer is 64.

Each cycle is having an difference of 2 ie,

16 - 9 = 7
25 - 16 = 9
36 - 25 = 11
49 - 36 = 13, so each answer is having a increase in 2 digit.

ie 7+2=9 and so on
so in the third round, we have 49 so add 49+(13+2)=49+15=64 hence answer.
