# Program for n-th even number

• Difficulty Level : Basic
• Last Updated : 25 Oct, 2018

Given a number n, print the nth even number. The 1st even number is 2, 2nd is 4 and so on.

Examples:

```Input : 3
Output : 6
First three even numbers are 2, 4, 6, ..

Input : 5
Output : 10
First five even numbers are 2, 4, 6, 8, 19..
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

The nth even number is given by the formula 2*n.

## C++

 `// CPP program to find the nth even number``#include ``using` `namespace` `std;`` ` `// Function to find the nth even number``int` `nthEven(``int` `n)``{``    ``return` `(2 * n);``}`` ` `// Driver code``int` `main()``{``    ``int` `n = 10;``    ``cout << nthEven(n);``    ``return` `0;``}`

## Java

 `// JAVA program to find the nth EVEN number`` ` `class` `GFG``{``    ``// Function to find the nth odd number``    ``static` `int` `nthEven(``int` `n)``    ``{``        ``return` `(``2` `* n);``    ``}``     ` `    ``// Driver code``    ``public` `static` `void` `main(String [] args)``    ``{``        ``int` `n = ``10``;``        ``System.out.println(nthEven(n));``         ` `    ``}``}`` ` `// This code is contributed``// by ihritik`

## Python3

 `# Python 3 program to find the ``# nth odd number`` ` `#  Function to find the nth Even number``def` `nthEven(n):`` ` `    ``return` `(``2` `*` `n)``     ` `# Driver code``if` `__name__``=``=``'__main__'``:``    ``n ``=` `10``    ``print``(nthEven(n))`` ` `# This code is contributed``# by ihritik`

## C#

 `// C# program to find the ``// nth EVEN number``using` `System;`` ` `class` `GFG``{``// Function to find the``// nth odd number``static` `int` `nthEven(``int` `n)``{``    ``return` `(2 * n);``}`` ` `// Driver code``public` `static` `void` `Main()``{``    ``int` `n = 10;``    ``Console.WriteLine(nthEven(n));``}``}`` ` `// This code is contributed``// by anuj_67`
