WebFor all integers m and n, if 2m +n is odd, then m and n are both odd. Solution To disprove the statement, we need to find integers m and n such that 2m +n is odd, and not both m and n are odd. Statement: ∀ integers m and n, if 2m +n is odd, then both m and n are odd. Counterexample: Let m = 2 and n = 1, then 2m +n = 5 which is odd, but not ... WebIf n is even but not 2 then n is composite D. n is prime and n is even but not 2 OE. n is prime or n is odd or n is 2 F. If n is composite then n is odd or n is 2 OG. n is prime …

WebA statement of the form ∃x ∈ D such that Q (x) is true if, and only if, Q (x) is true for at least one x in D. Let Q (n) be the predicate "n is a factor of 8." Find the truth set of Q (n) if the domain of n is the set Z+ of all positive integers. The truth set is {1,2,4,8} because these are exactly the positive integers that divide 8 evenly.
