Question

What should come in place of the question mark (?) in the given series?
31, 32, 41, 66, 115, ?

A.

167

B.

169

C.

196

D.

195

Correct option is C

Given: 31, 32, 41, 66, 115, ?​​
Logic: Difference of consecutive term is perfect square of odd number.
32 - 31 = 1 = 12​
41 - 32 = 9 = 32
66 - 41 = 25 = 52
115 - 66 = 49 = 72
Next perfect square of odd number is: 81 = 92
? - 115 = 81​
115 + 81 = 196
So, the missing term is 196.
Thus, correct option is (c).
