Isn't this a recursion? (Your Turn)

[angeliccanary]

Can't we just use the standard recursion formula or modular arithmetic or use the fact that we are finding GCD's of consecutive fibonacci numbers.
Please fell free to share other ideas about thsi problem

@angeliccanary Hi there! Thanks for these ideas. It's really cool when you can find more than one, or even several, ways of doing the same problem. You can definitely use the recursion definition of the Fibonacci sequence (which is very similar to what Prof. Loh did). I do think Prof. Loh was trying to find a different way to prove this pattern, rather than assuming the pattern was true, so I'm not sure about this:

Great job
