Question

Write an algorithm to find out sum of the series 1+2+3+4………N terms .

Answer 1

#include <iostream>

using namespace std;

int calcSeriesSum(int n){

int sumVar = 0;

for(int i = 1; i <= n; i++)

sumVar = sumVar + ( (i)*(i+1)*(i+2) );

return sumVar;

}

int main(){

int n = 7;

cout<<"The sum of series till "<<n<<" is "<<calcSeriesSum(n);

return 0;

}
