C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int n;
	double a=10,b=0;
	cin>>n;
	for(int i=1;i<=n;i++){
		b=b+a/2+a;
		a=a/2;
	}
	cout<<a<<endl;
	cout<<b<<endl;
	return 0;
}

Python :

# coding=utf-8
n = int(input())
i = 1
y = 10
z = 10
while (i <= n):
    y /= 2
    i += 1
    z += y*2
z -= y
print(y)
print(z)
