ightarrow P(k+1) \).
You would like to prove that \( P(n) \) is true for all positive integers. What is left for you to do ?
A. None of the other statement are correct.
B. Show that \( P(1) \) and \( P(2) \) are true, then use strong induction to conclude that \( P(n) \) is true for all positive integers.
C. Show that \( P(1) \) and \( P(2) \) are true, then use induction to conclude that \( P(n) \) is true for all positive integers.
D. Show that \( P(1) \), \( P(2) \) and \( P(3) \) are true, then use strong induction to conclude that \( P(n) \) is true for all positive integers.
