Question - 3, 2, 8, 9, 13, 22, 18, 32, 23, 42
A. 8
B. 9
C. 13
D. 22
Answer -
Option B
Explanation:
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.
