There is an extremely powerful tool in discrete mathematics used to manipulate sequences called the generating function. The simplest by far (and the easiest to generalize so that you can prove things about $R^i$ in general) is to note that $$x-z=x-y+y-z=c+c=2c.$$ Alternatively, note that $x=y+c$ and $y=z+c,$ so $x=(z+c)+c=z+2c,$ so $x-z=2c.$ So, we see that: Does this give you any inkling of what we can say about $R^i$ for $i\ge 1$ in general?
