ditions ui for all i = -5, -4, .., 0, are arbitrary non-zero real numbers. We also

ence equation

where the initial conditions are positive real numbers.
Theorem 5 Let {un}n=-5
be a solution to Eq. (10) and suppose that u-5 =
d, u-1 = e, uo = f. Then, for n = 0, 1,2, .., the
а, и-4 — б, и_з — с, и-2 —
