Short Inductive Proof
Need a little help on this proof...last one on the assignment can't figure it out.
For any integer k, show that k(k+1)(k+2) is congruent to 0 (mod 6).
Tried to prove this was divisible by 6 a few different ways but couldnt manage it. I believe this is related to induction. Thanks.
