# Find n-th term of series 1, 4, 27, 16, 125, 36, 343 …….

Given a number n, find the n-th term in the series 1, 4, 27, 16, 125, 36, 343……..

Examples:

```Input : 5
Output : 125

Input : 6
Output : 36
```

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

Naive approach : In this Sequence, if the Nth term is even then the Nth term is square of N else Nth term is a cube of N.

N = 5
In this case, N is odd
N = N * N * N
N = 5 * 5 * 5
N = 125

Similarly,
N = 6
N = N * N
N = 6 * 6
N = 36 and so on..

Implementation of the above approach is given below:

## C++

 `// CPP code to generate first 'n' terms ` `// of Logic sequence ` `#include ` `using` `namespace` `std; ` ` `  `// Function to generate a fixed \number ` `int` `logicOfSequence(``int` `N) ` `{ ` `    ``if` `(N % 2 == 0)  ` `        ``N = N * N;     ` `    ``else`  `        ``N = N * N * N;    ` `    ``return` `N; ` `} ` ` `  `// Driver Method ` `int` `main() ` `{ ` `    ``int` `N = 6; ` `    ``cout << logicOfSequence(N) << endl; ` `    ``return` `0; ` `} `

## Java

 `// JAVA code to generate first  ` `// 'n' terms of Logic sequence ` ` `  `class` `GFG { ` ` `  `// Function to generate ` `// a fixed \number ` `public` `static` `int` `logicOfSequence(``int` `N) ` `{ ` `    ``if` `(N % ``2` `== ``0``)  ` `        ``N = N * N;  ` `    ``else` `        ``N = N * N * N;  ` `    ``return` `N; ` `} ` ` `  `// Driver Method ` `public` `static` `void` `main(String args[]) ` `{ ` `    ``int` `N = ``6``; ` `    ``System.out.println(logicOfSequence(N)); ` `} ` `} ` ` `  `// This code is contributed by Jaideep Pyne `

## Python 3

 `# Python code to generate first  ` `# 'n' terms of Logic sequence ` ` `  `# Function to generate a fixed ` `# number ` `def` `logicOfSequence(N): ` `    ``if``(N ``%` `2` `=``=` `0``): ` `        ``N ``=` `N ``*` `N ` `    ``else``: ` `        ``N ``=` `N ``*` `N ``*` `N ` `    ``return` `N ` ` `  `N ``=` `6` `print` `(logicOfSequence(N)) ` ` `  `# This code is contributed by ` `# Vishal Gupta`

## C#

 `// C# code to generate first  ` `// 'n' terms of Logic sequence ` `using` `System;  ` ` `  `class` `GFG { ` ` `  `// Function to generate ` `// a fixed number ` `public` `static` `int` `logicOfSequence(``int` `N) ` `{ ` `    ``if` `(N % 2 == 0)  ` `        ``N = N * N;  ` `    ``else` `        ``N = N * N * N;  ` `    ``return` `N; ` `} ` ` `  `// Driver Method ` `public` `static` `void` `Main() ` `{ ` `    ``int` `N = 6; ` `    ``Console.Write(logicOfSequence(N)); ` `} ` `} ` ` `  `// This code is contributed by nitin mittal `

Output:

```36
```

Time Complexity : O(1)

My Personal Notes arrow_drop_up Strategy Path planning and Destination matters in success No need to worry about in between temporary failures
