If 5n · 5 3 5 6 then n is
WebBy assumption, n = 2k + 1 so 2n +6 = 5(2k +1) =6 = 10k + 11 = 10k +10 +1 = 2(5k +5) +1 = 5V +1 where v = (5k +5), so 5n +6 is odd. Second, we have to show that if 5n + 6 is odd then n is odd. Using indirect proves: Let n is event so n = 2k 5n +6 = 10k +6 = 2(5k +3) so it is event so by contraposition if 5n + 6 is odd then n is odd. From the two ...
