In this post we will write a **C++ program to display the sum of mathematics series**. first user will enter the a number for the base and then the number for power. and then program will print the sum and the series.

## C++ program to display the sum of mathematics series.

```
#include<iostream>
#include<conio.h>
int main()
{
system("cls");
double i,res,p,b;
float res2,n,n2;
std::cout<<"Enter the base of any number = ";
std::cin>>b;
std::cout<<"Enter the power of number = ";
std::cin>>p;
res = 1;
n = 0.0;
std::cout<<"The Series 1";
for(i=1;i<=p;i++)
{
res = res*b;
std::cout<<"+1/"<<res;
res2 = 1.0/res;
n = n+res2;
}
n2 = 1 + n;
std::cout<<" = "<<n2<<std::endl;
getch();
return 0;
}
```

### Output

Enter the base of any number = 4 Enter the power of number = 7 The series 1+1/4+1/16+1/64+1/256+1/1024+1/4096+1/16384 = 1.333313
