If m and n are positive integers is n even
WebFormalize: ∀integers m, n, if m and n are even then m + n is even 2. Suppose m and n are any even integers Existential Instantiation: If the existence of a certain kind of object is assumed or has been deduced then it can be given a name Since m and n equal twice some integers, we can give those integers names m = 2r, for some integer r and n ... Web30 dec. 2024 · With m = odd, we have m (m + 2) = Odd and m (m + 2) + 1 = m (m + 2) + Odd = Even. Thus, mn, the right-hand side = Even. Since m is odd, for mn to be even, n must be even. Sufficient. (2) m (m + n) is odd. We know that the product of two odd integers is odd, thus, for m (m + n) to be odd, m as well as (m + n) must be odd.
