#### 1. Introduction

It is very amusing to explore the nature of the solutions of a higher-order rational difference equation and to explain the local asymptotic stability of its equilibrium points. The inspection of some properties associated with these equations is a very enormous activity. Discrete dynamical systems or difference equations are diverse fields because various biological systems and models naturally lead to their study by means of a discrete variable. Applications of discrete dynamical systems and difference equations have appeared recently in many fields of science and technology. There is no doubt that the theory of difference equations will continue to play an important role in mathematics as a whole. Rational difference equations are a special form of nonlinear difference equations. Delay difference equations have rich dynamics to study. Due to adequate computational outcomes, discrete dynamical systems are awful lot better than allied structures in differential equations. Specifically, in case of nonoverlapping generations, difference equations are greater apposite to take a look at the behavior of population models [1, 2]. Also, an epidemiological approach to insurgent population modeling is mentioned in [3, 4]. The research of delay difference equations is a divergent field that involves most aspects of mathematics, including both applied and pure. Recently, there has been a symbolic development in the applications of difference equations. It is very interesting to investigate the behavior of solutions of a system of nonlinear difference equations and to discuss the local asymptotic stability of their equilibrium points. There are many papers in which systems and behavior of rational difference equations have been studied see [5–20]. Rational difference equations have been studied by several authors. There has been a great interest exclusively in the study of the attractiveness of the solution of such equations.

Here, we recall some basics and preliminaries that will be useful in our results and investigation.

#### 9. Concluding Remarks

In the literature, several articles are related to qualitative behavior of rational difference equations. It is a very interesting mathematical problem to study the dynamics of such equations because these are closely related to models in population dynamics and biological sciences. We have investigated the existence and uniqueness of positive equilibrium points, and boundedness and persistence of positive solutions are proved. Moreover, we have shown that they are locally as well as globally asymptotically stable. The main objective of dynamical systems theory is to predict the global behavior of a system based on the knowledge of its present state. We have taken some special cases as applications of equation (22) in Section 7 and found the closed form of the solutions. Finally, some illustrative examples are provided to support our theoretical discussion.
