ON QUADRAPELL NUMBERS AND QUADRAPELL POLYNOMIALS

Öz

In this paper we define and deal with the quadrapell numbers, D(n), in terms of a linear recurrence relation of order 4, and define the quadrapell polynomials in x. Further we give the generating function, a Binet-like formula and formulae for sums of these numbers.
