If n is a prime number, then n+1 is an even number

if n+1 is even, then n is prime (not necessarily so false)

if n = 9 then n+1 is even

but 9 = 3*3

contrapositive

if n+1 Is not even, then n is not prime (true if original statement is true, which it is)

I suspect that the original hypothesis should have stated greater than 2. That does not impact this problem because it is only asking for the converse and contrapositive.
