WebbIf 'n' is odd, then n 3 is also odd. This means that n 3 is not divisible by 8 and thus n 3 / 8 is simplified. Now we multiply both sides by 4 to give n 3 / 2 = 4x - 1. Now 4x - 1 is natural, but because n 3 is not divisble by 2, n 3 / 2 is not natural, giving us our final contradiction. [deleted] • 4 yr. ago.
