Matrices And Determinants

For a $2 \times 2$ matrix $A$, whose elements are real numbers, denote by $A^m$ the product $\underbrace{AA \cdots A}_{m \text{ times}}$, where $m$ is a positive integer. Define $x_0 = 0$, $x_1 = 1$, $x_n = x_{n-1} + x_{n-2}$, for all $n \geq 2$ and
$A_n = \begin{bmatrix} x_{n+1} & x_n \\ x_n & x_{n-1} \end{bmatrix}$, for all $n \geq 1$.
Which of the following statements is TRUE for all $m \geq 3$?
