WebbWhen n = 1, the left-hand side (LHS) of the equation becomes: Σ k = 1 to 1 k * (k + 1) = 1 * (1 + 1) = 2. And the right-hand side (RHS) becomes: (n(n + 1)(n + 2))/3 = (1(1 + 1)(1 + 2))/3 = 2/3. We can see that the base case holds true since LHS = RHS. Inductive Hypothesis: Now, let's assume that the formula holds true for some positive integer ...
