Answer 1

#include<iostream>
using namespace std;
float sum(float a, float d, int n) {
   float sum = 0;
   for (int i=0;i<n;i++) {
      sum = sum + a;
      a = a + d;
   }
   return sum;
}
int main() {
   int n = 10;
   float a = 2, d = 2;
   cout<<"sum of series A.P is : "<<sum(a, d, n);
   return 0;
}
