Question:

Find the wrong number in the following number series 3, 7, 16, 35, 70, 153.

Options:

153

Correct Answer:

Explanation:

The series →
3 , 7 , 16 , 35 , 70 , 153

The pattern is,

3 , 3(2)+1 = 7 , 7(2)+2 = 16 , 16(2)+3 = 35 , 35(2)+4 ≠ 70

Here , fifth term breaks the rule , So wrong number in series is 70.
