# Find Nth term of the series 3, 14, 39, 84…

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

3, 14, 39, 84…

Examples:

```Input: 3
Output: 39
For N = 3
Nth term = ( 3*3*3 ) + ( 3*3 ) + 3
= 39

Input: 4
Output: 84
```

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

Formula to calculate the Nth term of the series:

`Nth term = ( N*N*N ) + ( N*N ) + N `

Below is the required implementation:

## C++

 `// CPP program to find N-th term of the series: ` `// 3, 14, 38, 84... ` `#include ` `using` `namespace` `std; ` ` `  `// calculate Nth term of series ` `int` `nthTerm(``int` `N) ` `{ ` `    ``return` `(N * N * N) + (N * N) + N; ` `} ` ` `  `// Driver Function ` `int` `main() ` `{ ` `    ``int` `N = 3; ` ` `  `    ``cout << nthTerm(N); ` ` `  `    ``return` `0; ` `} `

## Java

 `// Java program to find Nth number ` `import` `java.io.*; ` ` `  `// calculate Nth term of this series ` `class` `GFG  ` `{ ` `public` `int` `nthTerm(``int` `N) ` `{ ` `    ``// By using above formula ` `    ``return` `(N * N * N) + (N * N) + N; ` `} ` ` `  `// Driver Code ` `public` `static` `void` `main(String[] args) ` `{ ` `    ``int` `N = ``3``; ` `    ``GFG a = ``new` `GFG(); ` ` `  `    ``// call and print Nth term ` `    ``System.out.println(a.nthTerm(N)); ` `} ` `} `

## Python 3

 `# Python 3 program to find  N-th  ` `# term of the series:  ` `# 3, 14, 38, 84...  ` ` `  `# Function to calculate Nth term of series   ` `def` `nthTerm(n) : ` ` `  `    ``return` `(N ``*` `N ``*` `N) ``+` `(N ``*` `N) ``+` `N ` ` `  `# Driver code ` `if` `__name__ ``=``=` `"__main__"` `: ` ` `  `     ``N ``=` `3` ` `  `     ``# function calling ` `     ``print``(nthTerm(N)) ` ` `  `# This code is contributed by ANKITRAI1 `

## C#

 `// C# program to find Nth number ` `using` `System; ` ` `  `// calculate Nth term of this series ` `class` `GFG  ` `{ ` `public` `int` `nthTerm(``int` `N) ` `{ ` `    ``// By using above formula ` `    ``return` `(N * N * N) + (N * N) + N; ` `} ` ` `  `// Driver Code ` `public` `static` `void` `Main() ` `{ ` `    ``int` `N = 3; ` `    ``GFG a = ``new` `GFG(); ` ` `  `    ``// call and print Nth term ` `    ``Console.WriteLine(a.nthTerm(N)); ` `} ` `} ` ` `  `// This code is contributed ` `// by inder_verma. `

## PHP

Output:

```39
```
