WebA proof by induction has two steps: 1. Base Case: We prove that the statement is true for the first case (usually, this step is trivial). 2. Induction Step: Assuming the statement is true for N = k (the induction hypothesis), we prove that it is also true for n = k + 1. There are two types of induction: weak and strong.

Base Case: For a 1 \times 1 1 ×1 square, we are already done, so no steps are needed. 1 \times 1 - 1 = 0 1×1 −1 = 0, so the base case is true.

Problem 1: Prove that 2 n + 1 < 2 n for all natural numbers n ≥ 3. Solution: Let P (n) denote the statement 2n+1<2 n. Base case: Note that 2.3+1 < 23. So P (3) is true. Induction hypothesis: Assume that P (k) is true for some k ≥ 3. So we have 2k+1<2k. how do absorption refrigerators work
