why is each number a product of 6?
The middle number is always even (between two odd numbers), so it’s divisible by 2. It’s also always divisible by 3, since for any 3 consecutive numbers, one must be divisible by three. The two primes are not divisible by 3, so the middle one must be. So the middle number is always divisible by 6. The only exception is 4, since the lower prime (3) is divisible by three.
