#### 1. Introduction

In recent years, many researchers have tended to use difference equations in mathematical models to explain the problems in different sciences since they have a lot of features such as they enable the scientists to introduce the predictions of their study and it gives more accurate results. In addition, there are various types of nonlinear difference equations that can be studied; one of the most commonly used is rational nonlinear difference equations. However, the research studies in the area of difference equations have two directions: first one is the analysis of the behavior of solutions. Therefore, there are a huge number of articles published to investigate the stability of the equilibrium points and the existence of the periodic solutions for the nonlinear difference equations (see, for example, ). The second direction is to obtain the expressions of the solution if it is possible since there is no explicit and enough methods to find the solution of nonlinear difference equations (see, for example, ).

This paper is collected as follows: in Section 2, the boundedness of the solution is presented, and we prove that the periodic solution of period two does not exist in the next section. Following that, we state the conditions of the local and global stability of the equilibrium point in Sections 4 and 5, respectively. Then, we introduce the solutions’ forms for some special cases in Section 6. Finally, we give some numerical examples in order to illustrate the behavior of the solutions.

#### 2. Boundedness of Solution

Theorem 1. If the following conditionis true, then every solution of (7) is bounded.

Proof. Assume that is a solution of (7). Then, from (7), we haveHence,Implies that the subsequences , , and are nonincreasing. Thus, they are bounded from above by , where .

#### 3. Periodicity of the Solution

Theorem 2. For nonlinear difference equation (7), there is no periodic solution of period two.

Proof. To prove Theorem 2, suppose that (7) has a positive prime period two solutions presented as . Then,Similarly,Subtracting (11) from (12), we getSince , thus , and this contradicts the fact that .

#### 4. The Equilibrium Point and Local Stability

The fixed points of (7) are given by

If , then (7) has only one equilibrium point which is .

Assume is a continuously differentiable function defined by

Therefore,

Then,

Hence,

Theorem 3. The fixed point is said to be a locally asymptotically stable if the relationis satisfied.

Proof. From Theorem 5.10 in , it follows that is asymptotically stable ifwhere and . Then,Hence,Finally, the proof is done.

#### 5. Global Attractivity of the Fixed Point

Theorem 4. The fixed point of (7) has to be a global attracting when

Proof. From (16), we see that the function , which defined in (15), is increasing in and decreasing in . Let be a solution of the system:Therefore,Subtracting (25) from (26), we getand then, if . Thus, from Theorem 5.20 in , we observe that there exists only one solution for (7) and it is a global attractor if .

#### 6. Special Cases

Now, we present the solutions’ expressions for special cases of (7):where the initial conditions areand are arbitrary real numbers.

##### 6.1. First Equation

Now, we prove that the results are satisfied for :From (30), it follows thatTherefore,Similarly, one can investigate other expressions. The proof is done.

##### 6.2. Second Equation

In this section, we introduce the solution of the following equation:

Theorem 6. Let be a solution of (35); then, for ,where is the Fibonacci sequence.

Proof. The proof will be the same as proof of Theorem 5, so it is therefore omitted.

##### 6.3. Third Equation

In this section, we present the solution of the following equation:

Theorem 7. Let be a solution of (37); then, for ,where .

Proof. By using mathematical induction, we prove that (38) are solutions of (37). First, the results for are true. Second, assume that the assumption holds for and .Now, from (37), we haveThus,Similarly, one can see that the other forms are true. The proof is complete.

##### 6.4. Fourth Equation

We study the following equation:

Theorem 8. Suppose that is a solution of (42), then there exists a periodic solution with period 54. Moreover, takes the form

Proof. The proof of this case will be the same as the proof presented for Theorem 7 and will be omitted therefore.

#### 7. Numerical Examples

To illustrate the solution behavior of (7) for various cases, we present some numerical examples.

Example 1. To show the stability of (7), we set two groups for the values of the coefficients: (i) and (ii) , and the initial conditions areand . The result is obtained in Figure 1. It is clear that (i) condition (23) is satisfied, which implies that the solution tends to the fixed point , while the solution moves away from the fixed point for (ii) since condition (23) failed.
The following examples have explained the solutions of special case equations (30)–(42).

Example 2. We choose the initial conditions asand . The solution is given in Figure 2.

Example 3. In Figure 3, we set the initial conditions:

Example 4. For (37), we choose the initial conditions asand then, the result is shown in Figure 4.

Example 5. We set the valuesThe solution is given in Figure 5. Clearly, the solution is periodic that means the result conforms with Theorem 8.
