C++Server Side ProgrammingProgramming

In this tutorial, we will be discussing a program to find sum of series 1*2*3 + 2*3*4+ 3*4*5 + . . . + n*(n+1)*(n+2)

For this we will be provided with the value of n. Our task is to calculate the sum of the series upto the given value and print it out.

Example

 Live Demo

#include <bits/stdc++.h>
using namespace std;
//calculating sum of series
int sumOfSeries(int n) {
   int sum = 0;
   for (int i = 1; i <= n; i++)
      sum = sum + i * (i + 1) * (i + 2);
   return sum;
}
int main() {
   int n = 10;
   cout << sumOfSeries(n);
   return 0;
}

Output
