I'm helping a friend design a user payout system (cryptocurrencies) for a sort of social network site and would like input for some questions posed.

Why is

(2n+1)^2 - 1

always divisible by 8?

Does this make 8 special somehow?

Does this generalize to other ways to generate mutliples of a given number by just computing values of a polynomial that doesn't even have that number in it in an obvious way?
