Answer 1

Answer:

#include<iostream>

using namespace std;

int main()

{

 int n;

 cin>>n;

 float a=0.5;

 for(int i=1;i<=n;i++)

 {

   cout<<a<<" ";

   a=a*3;

 }

 return 0;

}

Answer 2

Answer:

#include <iostream>

#include <cmath>

int main()

{

int n;

std::cin>>n;

double r=0.5;

for(int i=0;i<n;i++)

{

if(i==0)

{

std::cout<<r;

continue;

}

else

{

double t=pow(3,i-1);

double x=t+r;

r=x;

std::cout<<" "<<x;

}

}

}

Explanation:

In the above program some header files and included and for loop has been used with the suitable condition.

The output of the code will be the series 0.5, 1.5, 4.5, 13.5, up to the number of terms entered by the user.
