Answer 2

The sum of the first n odd numbers can be calculated using the formula `n^2`, where `n` represents the number of odd numbers . This formula is derived from the concept of arithmetic progression, where the common difference between odd numbers is 2.

In your case, you want to find the sum of the first 99 odd numbers. So, you can substitute `n` with 99 in the formula:

n^2 = 99^2

This will give you the sum of the first 99 odd numbers.

Here is how you can calculate it in Python:

n = 99
sum_of_odd_numbers = n**2
print(sum_of_odd_numbers)

When you run this code, it will print the sum of the first 99 odd numbers .

Remember, this formula only works when the first odd number is 1. If the sequence of odd numbers starts with a number other than 1, you would need to adjust the formula accordingly .
