# Program to find Nth term of series 0, 9, 22, 39, 60, 85, 114, 147, …..

Given a number N. The task is to write a program to find the Nth term of the below series:

0, 9, 22, 39, 60, 85, 114, 147…..(N Terms)

Examples:

```Input: N = 4
Output: 39
For N = 4
4th Term = ( 2 * 4 * 4 + 3 * 4 - 5)
= 39

Input: N = 10
Output: 224

```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Approach: The generalized Nth term of this series:

``` ```

Below is the required implementation:

## C++

## Java
