Answer:

There could be several answers.

You could add 27,000 each time (72,000)

or you could find what percentage 18,000 is of 45,000, then use that percentage of increase to figure out the next number for 45,000 (72,000)

Surprisingly, you will end up with 72,000 in both of these configurations.
