## Existence of nontrivial solutions of a rational difference equation.(English)Zbl 1131.39009

The author determines the asymptotic behaviour of a special solution of
$x_{n+1}= (x_n+ x_{n-1}+ x_{n-2} x_{n-3})/(x_n x_{n-1}+ x_{n-2}+ x_{n-3})$
which confirms a conjecture of L. Ladas [J. Difference Equ. Appl. 4, No. 5, 497–499 (1998; Zbl 0925.39004)] concerning the existence of a solution being not eventually constant.
