Is this discrete math question correct? Prove the following is true. If 7n+3 is odd, then n is even. *This is a proof by contrapositive?
My answer: Suppose n is odd.
So n= 2k+1 for some integer k.
7n+3=7(2k+1)+3= 14k+10 = 2(7k+5)
By definition, 7n+3 is even.
Since the contrapositive is true, that implies the origi... | HuggingFaceTB/finemath | |
