You have to look at the ones place digit for the quick way to this. If both ones digits are even then it will be even, if they are both odd then it will be even, if one is odd and one is even then it will be odd.

Use the prime factorizations to determine the GCF. If the GCF is 1, the numbers are relatively prime. If the two numbers have no prime factors in common, they are relatively prime.

If the prime factorizations have no prime factors in common, the numbers are relatively prime.

In order to determine whether or not this is an arithmetic sequence, there must be at least 3 numbers.

If at least one of the numbers is even, the result will be even. Otherwise all the numbers are odd and the result will be odd.

Well, there is a clear definition, and at least in theory you can always determine whether a number is a primer number or not, so I would say, yes.
