    Mathematical Induction (Pre-Calc)?

    Any help with these would be great :) 1. Use mathematical induction to prove the statement 4 + 8 + 12+…+4n = 2n(n+1) is true for all positive integers n. 2. When using math induction to prove that (n4 - 4n2) is divisible by 3 for all natural numbers. First, we will assume that (k4 - 4k2) is...
