# Program to find Nth term of series 0, 11, 28, 51, 79, 115, 156, 203, ….

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

0, 11, 28, 51, 79, 115, 156, 203…..(N Terms)

**Examples:**

Input: N = 4 Output: 51 For N = 4 4th Term = ( 3 * 4 * 4 + 2 * 4 - 5) = 51 Input: N = 10 Output: 314

**Approach:** The generalized Nth term of this series:

Below is the required implementation:

## C++

`// CPP program to find the N-th term of the series: ` `// 0, 11, 28, 51, 79, 115, 156, 203..... ` `#include <iostream> ` `#include <math.h> ` `using` `namespace` `std; ` ` ` `// calculate Nth term of series ` `int` `nthTerm(` `int` `n) ` `{ ` ` ` `return` `3 * ` `pow` `(n, 2) + 2 * n - 5; ` `} ` ` ` `// Driver code ` `int` `main() ` `{ ` ` ` `int` `N = 4; ` ` ` ` ` `cout << nthTerm(N) << endl; ` ` ` ` ` `return` `0; ` `} ` |
