what is the next number in this sequence 2 7 8 3 12 9

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?

 Sorry, but the terms do not match anything in the table. If your sequence is of general interest, please submit it using the form provided and it will (probably) be added to the OEIS! Include a brief description and if possible enough terms to fill 3 lines on the screen. We need at least 4 terms.

OK Goldenleaf, You and Jeff Aaron did a good job.

Now, what are the next sequences for this series 17, 29, 31, 48, 49, 34

Hint: These are from the Powerball lottery

There you go anonymous.

You got lots of attention and maybe some people learned about the OEIS foundation along the way!

2^3= 8

7^3= 343

8^3= 512

3^3 = 9

12^3 = 1728

9^3 = 729

28^3 = 21952

the serie will be then 2-7-8-3-12-9-28-29-52........

we take two terminal numbers if there is a repition 2 , 12 and 52

8 and 28
