The problem asks for the sum of the first 25 odd numbers.
There is a well-known formula for the sum of the first N odd positive integers. The sum is equal to N squared ($N^2$).
In this question, we need to find the sum of the first 25 odd numbers. This means our value for N is 25.
Therefore, the sum of the first 25 odd numbers is 625.
