## On the recursive sequence $$x_{n+1}=\alpha + x_{n-1}/x_n$$.(English)Zbl 1105.39008

A nonlinear difference equation having a ratio of two successive past values on the right hand side and with a negative coefficient and negative initial conditions is considered. Stability and periodic characteristics of the solutions are discussed.
