Given an infinitely convergent sequence pn with limit p, the forward difference is the measure of the difference between the current term and he next. The backward difference is the measure of the difference between the current term and the previous.i.e.forward difference: Δpn=pn+1 - pnbackward difference: ∇pn=pn - pn-1Also, note that since they are both expressed by pn, the forward difference is recognised by the use of a delta before the pn, and the backward difference by the use of a nabla.

Suppose Pk is the product of the first k numbers. P1 = 1 Pn = n*Pn-1 for n > 1 Curiously, though, when used for permutations or combinations (or for the Gamma function), P0 = Factorial(0) = 1
