This is tautology, and not worthy of consideration

Subject: [PrimeNumbers] When might I expect a prime or relative prime?

Hi all,

Would you consider this list A of primes including 2;

A = [2,3,5,7,11]

Then consider a number n.

n has these properties:

It is an even integer.

It is not divisible by any of the odd members of A.

Consider adding successively larger integer values x to n.

x has these properties:

It is odd.

It is divisible by any integer not in A

Can anyone give me any limitations on the size of gap within which I

would expect one of these additions to result in a prime or

relatively prime number?

Cheers for any consideration.
