It is the power method to obtain an eigenvector $v$ associated to the greatest eigenvalue (in absolute value) $\lambda$ of $A$ ; indeed $[x_n,y_n]^T=A^n[x_0,y_0]^T$, when $n$ is great enough, is s.t. $\dfrac{y_n}{x_n}\approx \dfrac{v_2}{v_1}$.

Here $\lambda=23+3\sqrt{13}$, $v=[9,6+3\sqrt{13}]^T$, and $\dfrac{v_2}{v_1}\approx 1.8685$.

For instance, $\dfrac{y_{12}}{x_{12}}\approx 1.8685$.
