I'm just going to grab a the formula and answer because this question needs to be answered.

2, 7, 8, 3, 12, 9 ...

The nth term of this sequence is:

-(17/30)n^5 + (113/12)n^4 - (173/3)n^3 + (1915/12)n^2 - (5813/30)n + 85

Therefore, term number 7 is: -146 / 1 = -146

Also, no luck with a book of sequences

This sequence is neither arithmetic or geometric, so I have no idea what comes next. Sorry :(

Maybe it is a sequence in a different base (not10)

Where does that online book of sequences hang out. Yes there really is such a thing.

Can anyone find it easily?
