Riddle Answer

The Combination Lock

After Andrew had been sick for a week, he asked his best friend Jesse to get his books out of his locker. Instead of telling Jesse the three number combination Andrew said he kept a small piece of paper with the combination under his locker door.

After school Jesse went to Andrew’s locker and pulled the paper. On the paper was written:
24 24 22 9 9 9 9 22 24 22 9 9.

Thinking this would be easy but a little tedious, Jesse entered in every arrangement of 24, 22, and 9 there was without the lock opening. Realizing there was something behind these numbers that he wasn’t noticing, Jesse sat down for a few minutes to think it out. After ten minutes of intense thinking, Jesse went to the locker, entered the combination into the lock and it opened.

What was the combination?
