## Homework Statement

## Homework Equations

## The Attempt at a Solution

This is what I have so far:

[tex]x_{n+1}=\frac{x^5_n + 1}{5x_n}=1[/tex]

[tex]x_{n+2}=\frac{x^5_{n+1} + 1}{5x_{n+1}}=\frac{1^5+1}{5}[/tex]

I think you have to do some sort of repeated substitution but I don't quite see it. Any help? Thanks.
