**Practical - 73 - Write a Python program to print the sum of first n odd natural numbers where the value of n is taken as input from the user.**

**Ans:**

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

sum=0

for i in range(1, 2*n, 2):

sum+=i

print("The sum of the first",n,"odd natural numbers is:",sum)

**Output:**

Enter the value of n: 3

The sum of the first 3 odd natural numbers is: 9

**OR**

Enter the value of n: 5

The sum of the first 5 odd natural numbers is: 25
