1$\begingroup$ I think this is a bit broad. You can answer any number, for example the solution of p(x)=(x-n)(x-12)(x-22)(x-35)... $\endgroup$– leoll2Commented May 2, 2015 at 11:56

1$\begingroup$ Usually in puzzles like this, one expects a rule to generate the entire sequence, not one that describes only some of the values including missing value. $\endgroup$– xnorCommented May 3, 2015 at 18:22
