I am a 2 digit number that ends in 4, but not divisible by 4. I found the answer (I think) is 24, 44, 64, 84. But I dont understand the pattern or the reason for the pattern. Can anybody help me? Thank you.

All the numbers you have listed are divisible by 4 !!. The rule for divisibility by 4 is this:

If the first TWO DIGITS of any number are EVENLY divisible by 4, then the whole number, no matter how big, is divisible EVENLY by 4. Example:3769321324. Since the last two digits, or 24, are EVENLY divisible by 4, then that whole number is EVENLY divisible by 4. And that is it.
