Find out the wrong term in the series 2, 3, 4, 4, 6, 8, 9, 12, 16

B) 12
C) 16
D) 8

Answer:

Explanation:
The given sequence is a combination of three series:
i)1st, 4th, 7th terms i.e, 2, 4, 9
ii)2nd, 5th, 8th terms i.e, 3, 6, 12
iii)3rd, 6th, 9th terms i.e, 4, 8, 16
In each one of i, ii, iii, each term is twice the preceding term.
So, 9 is wrong and must be replaced by (4*2) = 8
