C++Server Side ProgrammingProgramming

In this tutorial, we will be discussing a program to find N-th term of series 0, 10, 30, 60, 99, 150, 210, 280...

For this, we will be provided with a number. Our task is to find the term for the given series at that particular position.

Example

 Live Demo

#include <iostream>
#include <math.h>
using namespace std;
//calculating nth term of series
int nthTerm(int n) {
   return 5 * pow(n, 2) - 5 * n;
}
int main() {
   int N = 4;
   cout << nthTerm(N) << endl;
   return 0;
}

Output

60
