ABSTRACT

Consider the third-order rational difference equation

xn+1 = α+ βxn + γxn−1 + δxn−2 A+Bxn + Cxn−1 +Dxn−2

, n = 0, 1, . . . (2.0.1)

with nonnegative parameters α, β, γ, δ, A,B,C,D and with arbitrary nonnegative initial conditions x−2, x−1, x0, such that the denominator is always positive.
