Question

Fill in the blank:
2, 6, 15, 31, 56, ?​​

A.

92

B.

104

C.

100

D.

85

Correct option is A

Given: 2, 6, 15, 31, 56, ?​​
Logic: Numbers are increasing perfect square of natural number from 2.
2 + 4 = 6
6 + 9 = 15
15 + 16 = 31
31 + 25 = 56
Next perfect square: 62= 36
56 + 36 = 92
So, the missing term is 92.
Thus, correct option is (a).
