One term in the number series is wrong. Find out the wrong term.
3, 2, 8, 9, 13, 22, 18, 32, 23, 42

A. 8

B. 9

C. 13

D. 22

Answer: Option B

Solution(By Examveda Team)

The given sequence is a combination of two series:
I. 3, 8, 13, 18, 23 and II. 2, 9, 22, 32, 42
The pattern in I is + 5, and the pattern in II is + 10. So, in II, 9 is wrong and must be replaced by (2 + 10) i.e. 12.
