In following questions, one term in number series is incorrect.

Find out the incorrect number 6, 14, 30, 64, 126

Option:
A. 6
B. 14
C. 64
D. 126
Answer: C . 64

Justification:

Each term is multiplied by 2 and then increased by 2 to obtain the next term.
So, 64 is wrong and must be replaced by (30 * 2 + 2)  i.e. 62.
