Finding the next number in a sequence


I am usually good at doing these, but now I am stumped.  I cannot figure out the next sequence in this list of numbers.  Can anyone help me with this?

The numbers are:  10, 8, 7, 14, 15, 13, 12, 24 25

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.
