Abstract: In this paper an invariant of an equation with variable coefficients is first found. Then, by utilizing the invariant, the boundedness and persistence of solutions of the Lyness equation is derived. Our result partly solves an open problem given by G.Ladas.

Key words: variable coefficient, invariant, boundedness and persistence, Lyness' equation, variable coefficient, invariant, boundedness and persistence
