Question

Select the number that can replace the question mark (?) in the following series.
5, 12, 26, 54, ?, 222, 446

A.

110

B.

112

C.

116

D.

108

Correct option is A

Series: 5,12,26,54,?,222,446
Multiply by 2 + 2,
Starting with 5:
(5×2) + 2 = 10 + 2 = 12
Starting with 12:
(12×2) + 2 = 24 + 2 = 26
Starting with 26:
(26×2) + 2 = 52 + 2 = 54
Starting with 54:
(54×2) + 2 = 108 + 2 = 110
So, the missing term is 110.
