To prove 3+ 7+ 11 + ... + (4n − 1) = n(2n + 1) holds for an arbitrary n € Z+, in the inductive step, we first assume that Check ALL that apply, i.e. you are allowed to choose ONE or MORE answers. 77 P(k) : Σ(4k - 1) = n(2n + 1) k=1 72 P(n): (4n-1) = n(2n +1) j=1 72 P(n): (4j-1) = n(2n +1) j=1 n+1 P(n + 1): (4j-1) = (n + 1)(2(n + 1) + 1) j=1
