Write a C program to read in two numbers, x and n, and then compute the sum of this geometric progression: 1+x+x2+x3+………….+xn.

Write a C program to read in two numbers, x and n, and then compute the sum of this geometric progression: 1+x+x²+x³+………….+xⁿ.

#include<stdio.h>
int main()
{
   int x,n,i;
   long int s=1;
   printf(“Enter x,n values : “);
   scanf(“%d%d”,&x,&n);
   for(i=1;i<=n;i++)
      s=s+pow(x,i);
   printf(“Result = %ld\n”,s);
   return 0;
}

Output:

Enter x,n values : 10   6
Result = 1111111
