Answer 2

The number which comes next in the series is 7.

Given:

First 6 numbers of a series.

To Find:

The 7th number of the series.

Solution:

The first number = n = 4

The pattern in the series is: (n+3), (n+3-2), (n+3-2+3),.....

So, using this pattern, the formula for the 7th number will be: (n+3-2+3-2+3-2)

After substituting the value of n = 4 in the formula, we get 7.

The final answer is 7.
