# Hexacontatetragon numbers

Given a number N, the task is to find Nth Hexacontatetragon number.

An Hexacontatetragon number is a class of figurate numbers. It has a 64-sided polygon called Hexacontatetragon. The N-th Hexacontatetragon number count’s the 64 number of dots and all other dots are surrounding with a common sharing corner and make a pattern. The first few Hexacontatetragonol numbers are 1, 64, 189, 376, 625, 936, …

Examples:

Input: N = 2
Output: 64
Explanation:
The second Hexacontatetragonol number is 64.

Input: N = 3
Output: 189

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

Approach: The N-th Hexacontatetragon number is given by the formula:

• Nth term of s sided polygon = • Therefore Nth term of 64 sided polygon is Below is the implementation of the above approach:

## C++

 // C++ implementation for above approach  #include  using namespace std;     // Function to Find the   // Nth Hexacontatetragon Number  int HexacontatetragonNum(int n)  {      return (62 * n * n - 60 * n) / 2;  }     // Driver Code  int main()  {      int n = 3;      cout << HexacontatetragonNum(n);         return 0;  }

## Java

 // Java program to find N-th   // Hexacontatetragon number   class GFG{      // Function to find the nth   // Hexacontatetragon number   static int HexacontatetragonNum(int n)   {       return (62 * n * n - 60 * n) / 2;  }      // Driver code   public static void main(String[] args)   {       int n = 3;       System.out.print(HexacontatetragonNum(n));   }   }      // This code is contributed by shubham

## Python3

 # Python3 implementation for above approach     # Function to Find the   # Nth Hexacontatetragon Number  def HexacontatetragonNum(n):         return (62 * n * n - 60 * n) / 2;     # Driver Code  n = 3;  print(HexacontatetragonNum(n));     # This code is contributed by Code_Mech

## C#

 // C# program to find N-th   // Hexacontatetragon number   using System;  class GFG{      // Function to find the nth   // Hexacontatetragon number   static int HexacontatetragonNum(int n)   {       return (62 * n * n - 60 * n) / 2;  }      // Driver code   public static void Main()   {       int n = 3;       Console.Write(HexacontatetragonNum(n));   }   }      // This code is contributed by Code_Mech

Output:

189
