Web1 aug. 2024 · Prove by induction that for all natural numbers n, T(n) = 4 n - (-1) n. The following is my logic, since I have to prove T(n+1), I have to prove T(n+1) = 4 n+1 - (-1) n+1. Base Case: T(0) = 4 0 - (-1) 0 = 1 - 1 = 0. Induction Step: Assume T(n), prove T(n+1). I want to prove that 3T(n-1) + 4T(n-2) + (n+1) = 4 n+1 - (-1) n+1. 1. 3T(n-1) + 4T(n-2 ... Web2.Prove that if S(n) is true for all possible values of n from n 0 up to k, where k t, then it is also true when n = k + 1.
