Answer 2

Answer:

#include<bits/stdc++.h>

using namespace std;

int main()

{

for(int i=0; i<=3; ++i)

{

for(int j=0; j<2; ++j)

{

if(i==0)

cout<<"0";

cout<<pow(2,i);

}

}

return 0;

Explanation:

Series is increasing exponentially as 0, 2¹, 2², 2³.....

First for loop will take care of increasing power and second for loop will handle the number of prints you want, in this case it's printing twice every time.
