Explanation:
Sum of square of first n even numbers
Given a number n, find sum of square of first n even natural numbers.
Examples :
Input : 3
Output : 56
22 + 42 + 62 = 56
Input : 8
Output : 816
22 + 42 + 62 + 82 + 102 + 122 + 142 +162
A simple solution is to traverse through n even numbers and find the sum of square.
// Simple C++ method to find sum
// of square of first n even numbers.
#include <iostream>
using namespace std;
int squareSum(int n)
{
int sum = 0;
for (int i = 1; i <= n; i++)
sum += (2 * i) * (2 * i);
return sum;
}
// Driver Code
int main()
{
cout << squareSum(8);
return 0;
}
Output:
816
