The main objective of this paper is to study the global behavior and oscillation of the following third-order rational difference equation xn+1=αxnxn-1xn-2/βxn-12+γxn-22, where the initial conditions x-2,x-1,x0 are nonzero real numbers and α,β,γ are positive constants such that α≤β+γ. Visual examples supporting solutions are given at the end of the study. The figures are found with the help of MATLAB.
