  In this paper we show that two of the Worpitzky Number Triangles, OEIS
A028246 and A019538, may each be used in look-up table fashion, along with
specific diagonals of a polynomial sequence's difference triangle to easily
solve for the unknown coefficients of the sequence. This is accomplished by
using a method that isolates each of the coefficients as a single unknown in a
series of simple linear equations. The method is first applied to a sequence
generated using integer indexes with a starting index of 0, using the Alternate
Worpitzky Number Triangle, A019538. Although the numbers in A019538 are less
commonly referred to as a Worpitzky Number Triangle, a justification for such a
reference is briefly presented. Next, the method is applied to a sequence
generated using integer indexes with a starting index of 1, using the Mirrored
Worpitzky Number Triangle, A028246. The method is then extended to solve for
the coefficients of a sequence generated with input data consisting of an
arbitrary starting number and an arbitrary constant differential.
