Most natural phenomena arising in nonlinear sciences can be often described using difference equations. This work aims to extract some new analytic solutions for some rational difference equations of twentieth order. We also investigate local and global stability, periodic behavior, oscillation, and boundedness of the constructed solutions. The solutions are obtained using the iteration method and the modulus operator. Moreover, the obtained results are confirmed with some numerical examples which have been plotted with the help of MATLAB software. The proposed approaches can be simply applied for other high-order difference equations.
