65=5x13,
X =?,
75=5x15

Then X= 67,71, 73

To say a thing like that is to confirm that the distinction between odd and even is more of a language concept than a numerical concept. You could also say that it is significant that among all the even numbers, 2 is the only prime one, compared with quite a lot of primes among the odd numbers. The real anomaly with 2 as a prime is because it is so small. For all other primes P, the number 1 behaves in a certain way relative to it, and the number P-1 behaves in a certain other way. When P is 2, the numbers 1 and P-1 are identical.
