# Program to find the Nth term of the series 0, 5, 18, 39, 67, 105, 150, 203, …

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

0, 5, 18, 39, 67, 105, 150, 203, …(N Terms)

Examples:

```Input: N = 4
Output: 82
For N = 4
4th Term = ( 4 * 4 * 4 - 7 * 4 + 3)
= 39

Input: N = 10
Output: 332

```

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, 5, 18, 39, 67, 105, 150, 203, ... ` `#include ` `#include ` `using` `namespace` `std; ` ` `  `// calculate Nth term of series ` `int` `nthTerm(``int` `n) ` `{ ` `    ``return` `4 * ``pow``(n, 2) - 7 * n + 3; ` `} ` ` `  `// Driver code ` `int` `main() ` `{ ` `    ``int` `N = 4; ` ` `  `    ``cout << nthTerm(N); ` ` `  `    ``return` `0; ` `} `

## Java

 `// Java program to find the N-th term of the series:  ` `// 0, 5, 18, 39, 67, 105, 150, 203,  ` ` `  `import` `java.util.*; ` `import` `java.lang.*; ` `import` `java.io.*; ` ` `  `class` `GFG ` `{ ` `// calculate Nth term of series  ` `static` `int` `nthTerm(``int` `n)  ` `{  ` `    ``return` `4` `* (``int``)Math.pow(n, ``2``) - ``7` `* n + ``3``;  ` `}  ` `   `  `// Driver code  ` `public` `static` `void`  `main(String args[])  ` `{  ` `    ``int` `N = ``4``;  ` `   `  `    ``System.out.print(nthTerm(N));  ` `}  ` `}  `

## Python 3

 `# Python 3 program to find the  ` `# N-th term of the series: ` `# 0, 5, 18, 39, 67, 105, 150, 203, ... ` ` `  `# calculate Nth term of series ` `def` `nthTerm(n): ` ` `  `    ``return` `4` `*` `pow``(n, ``2``) ``-` `7` `*` `n ``+` `3` ` `  `# Driver code ` `N ``=` `4` ` `  `print``(nthTerm(N)) ` ` `  `# This code is contributed by ash264 `
