I think the problem must have been a misprint.  If the sequence is instead
17, 663, 25857, 1008423,   then the terms are 17 * 39^n.

I will be away from email during that period.

Apologies for such a trivial message, but otherwise I've found
that people complain if the database isn't updated every few days.

As long as I'm sending this out, let me mention two recent unsolved
problems, both found in school books:  Apparently both of them say
"Find the next term in ..."
