Number Series Q2

2.Find out the incorrect number 11, 2, 21, 3, 32, 4, 41, 5, 51, 6

A. 21       B. 11       C. 32       D. 51     

Answer:      C . 32

Explanation:     

The given sequence is a combination of two series :

I.   11, 21, 32, 41, 51   and

II.   2, 3, 4, 5, 6.

Clearly, the pattern in I is + 10.

So, 32 is wrong and should be replaced by (21 + 10)  i.e. 31
