    Solution Preview

    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 ...

    Solution Summary

    The proof by contradiction method is demonstrated in this solution to show that if 3n + 2 is even, n is even as well.
