Answer 2

Given:

The series $5,13,32,73,7,331,68$

To Find:

We need to find the next number in the series

Solution:

In these sums in which we need to find the number in the series, we can see that it always follows in the particular sequence.

In this series the formula used is

$5$×$2$ $+3$, $13$×$2+6$, $32$×$2$$+9$, $73$×$2+9$, $158$×$2+15$

In this way be using the formula we can say that the missing number which we have found is $158$

So the correct option is B which is given as $158$

Hence the series is $5 ,13 ,32,73 , 158 ,331$
