Can odd numbers be composite
WebWe know that every odd number can be expressed as 2k+1, where k is a positive integer. 2 k + 1 = k + ( k + 1). Hence, every odd number can be expressed as the sum of two consecutive positive integers. So, we have also proved that every odd prime number can be expressed as the sum of two consecutive positive integers. WebThus, 5k is composite. Since 33 is odd and composite, m is even, 5k should be odd as well. If m = 4 mod 5, we can express m = 9 + 5k for some integer k. Since , so . Thus, 5k is composite. Since 9 is odd and composite, m is even, 5k should be odd as well. Thus, in all cases we can split m into 2 odd composites, and we get at a contradiction ...
