Thank you, Victor, for mentioning that.

You’ll have to investigate the pattern a bit further to understand what it does exactly because your understanding of it is inside-out right now.

The pattern does not point out prime numbers; it is a pattern that particularly appoints which numbers in first and fifth places are NOT prime numbers. Starting with prime number 5 (as we both know, 2 and 3 are already left out of the equation), this number is used like a bowling ball, eternally throwing down pins along the way.

The prime numbers are the pins left standing; all balls missed them. Nothing happened to them.

A pin that was thrown down will stay down. Additional balls do not throw the pin down a second time. Once a pin is down, that’s it.

25 is downed by 5. Multiplications of 25 are just part of the pattern, but do not effect pins to be thrown down a second time.

The pattern is intact.

I like your remark, because it means you are interested in the building blocks of math. You are not the first one to have made this comment.

Please follow up and challenge me with anything else you see about this pattern. So far, no one has been able to declare that it is an incorrect pattern, but no one has gotten further than your remark either.
