Sequences

[geodave]

Actually, mine was an alternate fibonnaci sequence starting with 0 and 2, but it amounts to the same thing.

10, 10, 10, 15, 10, 10, 15, 10, 40, __

That's tricky. Looks sort of like a tennis score.

Let's try the difference method

0,0,5,-5,0,5,-5,30

0,5,-10,5,5,-10,35

5,-15,15,0,-15,45

-20,30,-15,15,60

50,-45,30,45

-95,75,15

180,-60

-240

-240,-240

180,-60,-300

-95,75,15, -285

50,-45,30,45,-240

-20,30,-15,15,60,-180

5,-15,15,0,-15,45,-135

0,5,-10,5,5,-10,35,-100

0,0,5,-5,0,5,-5,30,-70

which would make the next number -30. I'm guess that's NOT what you were looking for.
