:eek:

My brain is fried from doing vector analysis all day. No way I'll ever be able to figure that out.

Break it into two sub-series:
(20,18,13...) and (1,4,...)
Obviously in the 2nd series numbers are increasing for 3.
Now for the first one.
20-18=2-1=1
18-13=5-1=4
Looks like we're getting the numbers of the 2nd series. Following this logic I get 7,5,10 as the next tree numbers.

Of course I may be completely off with this :D

Hillarious!! http://www.tombraiderforums.com/images/smilies/jumper.gif
Good thing I didn't bother to do this big calculation then after reading those first numbers http://www.tombraiderforums.com/images/smilies/tongue.gif
Then I probably would have been throwing darts at a certain someone!! http://www.tombraiderforums.com/images/smilies/tongue.gif
