"In fact, so long as the absolute difference between the two values to be square rooted is the same integer, the property will hold."

- What square rooting?

In your last section, I'd take out the word painless... maybe replace it with something else.

Also, in that section, you say "using the fact that a_1" without stating any fact. Your next step is unclear without that statement.

Your example doesn't make sense to me. Between 25 and 125, you add 100, but then between 125 and 625 is 500... and it's a geometric series, and not the series you gave as series 1. You also need to fix your formula. It should be .

Once you've made the basic math revisions to the page, we can work on style changes.
