Write a c++ program for the sequence, ∑_(i=1)^n=2^(3^i )/i=2^(3^1 )/1+2^(3^2 )/2+2^(3^3 )/3+⋯+2^(3^n )/n if the manual input is n.

Answer 1

#include <iostream>

using namespace std;

//main function
int main()
{
int n=0;
cout<<"Enter n: ";
cin>>n;//enter n
int sum=0;
for(int i=1;i<n;i++){
sum+=pow(2,(pow(3.0,i)/i));
}
//show result
cout<<"Sum = "<<sum;
cin>>n;//delay
return 0;
}
