Use the Principle of Mathematical Induction to show that the statement is true for all natural numbers n.Show that the statement " is a prime number" is true for , but is not true for .

What will be an ideal response?


When , which is a prime number, so the statement is true when . When , which is not a prime number, so the statement is not true for .
