1. The problem statement, all variables and given/known data Prove that the following is divisible by 228 for any n (natural number). [tex]1561^n + 712^n -1225^n - 364^n [/tex] 2. Relevant equations 3. The attempt at a solution I'm guessing you have to prove by induction. When n = 1, the quotient is 3. What do I do afterwards? Thanks.
