For each positive integer n, let P(n) be the formula 12 + 22 ++ n2 = n(n + 1)(2n + 1) 6
Chapter 5, Problem 3(choose chapter or problem)
For each positive integer n, let P(n) be the formula
\(1^{2}+2^{2}+\cdots+n^{2}=\frac{n(n+1)(2 n+1)}{6}\)
a. Write P(1). Is P(1) true?
b. Write P(k).
c. Write P(k + 1).
d. In a proof by mathematical induction that the formula holds for all integers n ≥ 1, what must be shown in the inductive step?
