Program to find Nth term of series 0, 9, 22, 39, 60, 85, 114, 147, …..
• Last Updated : 10 Mar, 2021

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```

Approach: The generalized Nth term of this series:

` `

Below is the required implementation:

## C++

 `// C++ program to find the N-th term of the series:``// 0, 9, 22, 39, 60, 85, 114, 147.....``#include ``#include ``using` `namespace` `std;` `// calculate Nth term of series``int` `nthTerm(``int` `n)``{``    ``return` `2 * ``pow``(n, 2) + 3 * 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, 9, 22, 39, 60, 85, 114, 147.....` `public` `class` `GFG {``    ` `    ``// calculate Nth term of series``    ``static` `int` `nthTerm(``int` `n)``    ``{``        ``return` `2` `* (``int``)Math.pow(n, ``2``) + ``3` `* n - ``5``;``    ``}``      ` `    ``// Driver code``    ``public` `static` `void` `main(String args[])``    ``{``        ``int` `N = ``4``;``          ` `       ``System.out.println(nthTerm(N));``    ` `    ``}``    ``// This Code is contributed by ANKITRAI1``}`

## Python3

 `# Python3 program to find the``# N-th term of the series:``# 0, 9, 22, 39, 60, 85, 114, 147.....` `# calculate Nth term of series``def` `nthTerm(n):` `    ``return` `2` `*` `pow``(n, ``2``) ``+` `3` `*` `n ``-` `5` `# Driver code``N ``=` `4``print``(nthTerm(N))` `# This code is contributed by``# Sanjit_Prasad`

## C#

 `// C# program to find the``// N-th term of the series:``// 0, 9, 22, 39, 60, 85, 114, 147.....``using` `System;` `class` `GFG``{` `// calculate Nth term of series``static` `int` `nthTerm(``int` `n)``{``    ``return` `2 * (``int``)Math.Pow(n, 2) +``                        ``3 * n - 5;``}` `// Driver code``public` `static` `void` `Main()``{``    ``int` `N = 4;``    ` `    ``Console.WriteLine(nthTerm(N));``}``}` `// This Code is contributed``// by Akanksha Rai(Abby_akku)`
