Question 4. Prove using mathematical induction that for any integer n 0, 3n+1 1 1+3+32 +3" 2 P(n) Basis step: (Write what is P(0) and show that P(0) is true.) Induction step: For any k 0, if P(k) (write out P(k)) is true, then P(k + 1) (write out P(k + 1)) is also true. Proof of the induction step: The conclusion (by the principle of mathematical induction): Question 4.
