# Program for n-th even number

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
