In other words, error is approximately $|x_{n+1}-x_n|$ (absolute) or $|1-x_{n+1}/x_n|$ or, equivalently, $|1-x_n/x_{n+1}|$ (relative).

@Totty No, you never have the real value, after all, your numerical procedure is only there so you can approximate it. Your notions of error (both absolute and relative) come from consecutive sequence terms, with the notion that once you start approaching the true value (supposedly the limit of your value sequence), the size of the steps will start coming down (until, theoretically, it is 0 at the limit point). The whole idea is that the current step size gives an approximation for the real error. But again, since the real value isn't known, true error isn't known either - only approximation.

Remains to prove that "neither is true" is impossible.

It's not $3^3$ but $3^2$ in the denominator's right factor under the square root....

comment Existence of a stationary distribution for a random walk
Are you saying the number of neighbors (i.e. the degree) of each vertex is the same, or just uniformly bounded? If not the same, is it random?

What exactly are you trying to model? What is the probabilistic part of the experiment?
