One term in the number series is wrong. Find out the wrong term.
15, 16, 22, 29, 45, 70

A. 16

B. 22

C. 45

D. 70

Answer: Option B

Solution(By Examveda Team)

The correct pattern is + 1, + 4, + 9, + 16, + 25 i.e. + 1², + 2², + 3², + 4², + 5².
So, 22 is wrong and must be replaced by (16 + 4) i.e. 20.
