Textbook says that $\sqrt{2}-1$ is one solution.

comment Solving logarithmic equation?
In the textbook, solutions are $\sqrt{2}-1$ and $-\sqrt{2}-1$. I know this "hunting lion" method, but exact solutions exists.

comment How do I $n\lambda ^n$ tends to $0$?
Yes: $\lim_{x\rightarrow \infty}\frac{\lambda^x}{\frac{1}{x}}$ gives me the indetermination "$0$/$0$" and I need to see the behaviour of $$\frac{ln(\lambda ) \lambda^x}{\frac{-1}{x^2}}$$

comment Prove that a sequence is a Cauchy sequence.
What happens if we have $|s_{n+1}-s_n|< \frac{1}{n}$?

The initial problem is with $k=3$, but I'm thinking about consequences if $k$ is a real positive number.
