Logic :-

 We can clearly seen that series x^0+x^1+x^2+x^3 and so on so first we enter value of 'X' then number of terms after that we calculate sum of series upto n'th terms.In the last print the sum of series .

#include<iostream>
#include<math.h>
using namespace std;
int main()
{

 long i,n,x,sum=1;

 cout<<"\n1+x+x^2+……+x^n";
 cout<<"\nEnter The Value Of X and n :\n";
 cin>>x>>n;

 for(i=1;i<=n;++i)
 {
  sum+=pow(x,i);
 }
 cout<<"\nSum = "<<sum<<endl;
 return 0;
}

 

Output:

1+x+x^2+……+x^n

Enter The Value Of X and n :

2

3

Sum = 15
