Let's look at the first 5 Pythagorean Triples:

3-4-5, 5-12-13, 7-24-25, 9-40-41, 11-60-61

Are you noticing a pattern here?

The first number in each triple is just 3, 5, 7, 9, 11, adding 2 each time.

The second number in each triple is 4, then 12 (adding 8), then 24 (adding 12), then 40 (adding 16), then 60 (adding 20). You add 4 to the number you add to the number every time.

The third number in each triple is always just the second number + 1.

Here is a Python 3.4 algorithm to simulate this (sorry for bad quality).

Please let me know if you can find a proof for this algorithm.
