Please explain on how to get the sum of all even numbers between 253 and 453. Thanks!

There are several ways to do this. What class are you doing this for? Pre-calc? If so, I should think you might be wanting an arithmatic series, starting at n=254 and ending at n=452, for that. Otherwise, you can write a formula using the range of values, halved.
