Assume that n is a positive integer. Use the proof by contradiction method to prove and explain if 3n + 2 is an even integer then n is an even integer.© BrainMass Inc. brainmass.com October 10, 2019, 3:32 am ad1c9bdddf
As the proof needs to be given using contradiction method,
Let us suppose that 3n+2 is an even integer but n is NOT an even integer.
This means, n should be an odd ...
The proof by contradiction method is demonstrated in this solution to show that if 3n + 2 is even, n is even as well.
