Adding four and subtracting one is the same as adding three. So, to see if a number can be in this pattern, subtract five and check if the result is a multiple of three. If it is, it can be in the pattern.

Fun fact: to check if something is a multiple of three, add all the digits up and see if that is a multiple of three. If you don't know, repeat the process of adding the digits.
