# Program to find Nth term of series 0, 10, 30, 60, 99, 150, 210, 280………..

• Last Updated : 07 Aug, 2022

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

0, 10, 30, 60, 99, 150, 210, 280…..(N Terms)

Examples:

```Input: N = 4
Output: 60
For N = 4
4th Term = ( 5 * 4 * 4 - 5 * 4)
= 60

Input: N = 10
Output: 449```

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, 10, 30, 60, 99, 150, 210, .....``#include ``#include ``using` `namespace` `std;` `// calculate Nth term of series``int` `nthTerm(``int` `n)``{``    ``return` `5 * ``pow``(n, 2) - 5 * n;``}` `// 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, 10, 30, 60, 99, 150, 210, .....``import` `java.util.*;` `class` `solution``{` `// calculate Nth term of series``static` `int` `nthTerm(``int` `n)``{``    ``return` `5` `* (``int``)Math.pow(n, ``2``) - ``5` `* n;``}` `//Driver code``public` `static` `void` `main(String arr[])``{`` ` `     ``int` `N = ``4``;``     ``System.out.println(nthTerm(N) );` `}``}` `//This code is contributed by Surendra_Gangwar`

## Python3

 `# Python3 program to find the``# N-th term of the series:``# 0, 10, 30, 60, 99, 150, 210, .....` `# calculate Nth term of series``def` `nthTerm(n):` `    ``return` `5` `*` `pow``(n, ``2``) ``-` `5` `*` `n` `# 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, 10, 30, 60, 99, 150, 210, .....``using` `System;` `class` `GFG``{` `// calculate Nth term of series``static` `int` `nthTerm(``int` `n)``{``    ``return` `5 * (``int``)Math.Pow(n, 2) - 5 * n;``}` `// Driver code``public` `static` `void` `Main()``{``    ``int` `N = 4;``    ``Console.Write(nthTerm(N));``}``}` `// This code is contributed``// by ChitraNayal`

## Javascript

Output:

`60`

Time Complexity: O(logN) since using inbuilt pow function

Space Complexity: O(1) since using constant variables
