Question:

DIRECTIONS: Find the wrong term in the given series:


2, 3, 5, 8, 17, 33 

Options:
A)

33

B)

17

C)

8

D)

5

Solution:

Ans: (c)

In the series each term is less than twice the preceding term by 1.

The series is 2, (2 × 2 - 1) = 3, (3 × 2 - 1) = 5, (5 × 2 - 1) = 9, (9 × 2 - 1) = 17, (17 × 2 - 1) = 33

So 8 is wrong and it is replaced by 9.
