Where x is the xth term of the sequence, and where the intermediate calculations are non-zero integers:
The first term of the polynomial appears to follow the pattern
The second term of the polynomial appears to follow the pattern
The third term of the polynomial appears to follow the pattern
The coefficient of each n term of the polynomial appears to follow the pattern  [x*(x+1)].
The other patterns remain obscure, I selected one to post here from the several possible.
