# 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

```

## 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++

 `// CPP program to find the N-th term of the series: ` `// 0, 11, 28, 51, 79, 115, 156, 203..... ` `#include ` `#include ` `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; ` `} `

## Java

 `// Java program to find the  ` `// N-th term of the series: ` `// 0, 11, 28, 51, 79, 115, 156, 203..... ` `import` `java.io.*; ` ` `  `class` `GFG  ` `{ ` ` `  `// calculate Nth term of series ` `static` `int` `nthTerm(``int` `n) ` `{ ` `    ``return` `3` `* (``int``) Math.pow(n, ``2``) +  ` `                           ``2` `* n - ``5``; ` `} ` ` `  `// Driver code ` `public` `static` `void` `main (String[] args) ` `{ ` `    ``int` `N = ``4``; ` ` `  `    ``System.out.println(nthTerm(N)); ` `} ` `} ` ` `  `// This code is contributed  ` `// by anuj_67 `
