"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?
also what absolute difference are you talking about?
Actually, this sentence and the following equation could probably just be replaced by "the nth term of a sequence is the average of the (n-t)th term and the (n+t)th term".

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.

Rather than terms "increasing" don't you want terms "changing"? For e.g. 2, for example.

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 $a_n=a_0+d*n$ .
