Class 11 CS Practical - 43

 43 - Write a program in Python to input the value of x and n and print the sum of the following series:

1 + x + x2 + x3 +x4 + -------- xn

x=int(input("Enter the value of x: "))

n=int(input("Enter the value of n: "))

sum=0

for i in range(0,n+1):

    sum=sum+pow(x,i)

print("Sum of the series=",sum)


Output:

Enter the value of x: 2
