Ive been working this sequence for over a year now . Please help anyone
2,7,8,1,7,4,2,8,4,8,2,1,5,4,7,5,7,7,5,8,
there are two more numbers to the sequence but I just have not been able to get them Please help

There are twenty numbers: $\displaystyle a_1,\ldots,a_{20}$ in your sequence. If I have understood correctly your question, you want to find $\displaystyle a_{21}$ and $\displaystyle a_{22}$ finding a determined rule. Well, in that case the correct answer is $\displaystyle a_{21}=\alpha$ and $\displaystyle a_{22}=\beta$ being $\displaystyle \alpha$ and $\displaystyle \beta$ chosen at random. And all of his as a consequence of a well known result about the Lagrange interpolation polynomial.

I can see why you think that a math help forum might be the place for this problem, but I suspect that the answer may not involve mathematics at all. If I had to guess, I would suspect that these numbers might perhaps be the lengths of the words in some saying, poem, song, something like that?
Where did this sequence come from, and how do you know that there are only two more elements in it? If you can give us something of the background to the problem, it might give some clues about what the sequence represents.
When I see such a sequence the first thing I do if the general form is not obvious is search the Online Encyclopedia of Integer Sequences, and lo - it knows this sequence not.
(this is probably a neopets puzzle)
