Using the definitions of even integer and odd integer, give a proof by contraposition that this statement is true for all intege
kvasek [131]
Suppose n is even, i.e. there is some integer k such that n=2k. Then

3n-5=3(2k)-5=6k-5=6k-6+1=2(3k-3)+1=2K+1

where K is just some other integer. Therefore 3n-5 is odd, proving the contrapositive, and so the original statement is also true.
