11. Which of the following is a necessary step in proof by induction?
12. If P(k) is true, and we prove P(k) ⇒ P(k+1), then by induction P(n) is true for all n ≥ 1. This is the principle of:
13. The sum of cubes of first n natural numbers is:
14. Using induction, to prove 1² + 2² + ... + n² = n(n+1)(2n+1)/6, the inductive step adds:
15. The base case for proving 2ⁿ ≥ n² for n ≥ 4 is:

16. If we prove P(1) and P(k) ⇒ P(k+1), we can conclude P(n) is true for:
17. The statement 1 + 3 + 5 + ... + (2n-1) = n² is proven by induction. The base case is n = 1, LHS=1, RHS=1. In the inductive step, the sum for n=k+1 becomes:
18. For the inequality 2^n > n for all n ≥ 1, the inductive step shows that 2^(k+1) > k+1 using the assumption 2^k > k. How?
19. The sum 1 + 2 + 4 + ... + 2^{n-1} equals:
20. To prove that 3 divides n³ - n for all natural numbers n, induction is used. The base case n=1 gives 1³-1=0, divisible by 3. In the inductive step, we add:
