Is everything part of a sequence?

I wonder if there is a sequence 
(Nickh, a math blogger, found the solution to an old problem I posed. Turns out, the answers form a known sequence)

If you plan to work on this, please note A087774 eliminates all numbers two more than a multiple of 3 (ie, 5, 8, 11,…) from consideration.
I don’t know if there is an interesting sequence with that property, but it certainly is true that for any finite list of numbers there is a polynomial f such that that list is the beginning of the sequence f(0), f(1), f(2), …
So we can write a polynomial such that f(0) = 1, f(1) = 2, f(2) = 87 (eg.
),
but the OnLine Dictionary of Integer Sequences has nothing listed.
So 87 comes first.
(and yes, I manually checked 1 – 86. Can’t be the best way…)
Hey, it was me who posted about A078511, not that I’d say that constituted finding a solution to your original problem!
Puzzle Nick! not worksheet Nick! I should have figured. He’s a nice guy, too.
Didn’t I cheat you credit once before? I need to work on that. And I’ll go fix the post.
In any case, thanks for the Sequence, and thanks for the heads up!
