Hi, I had difficulty solving this problem. Actually, I'm stuck.
Suppose (Xn) in R is defined recursively by X1= 1 and , n= 1, 2, ...
Show (Xn) converges and find its limit.
And there's a hint: Notice that | Xn+2 - X n+1| < 1/9 |Xn - Xn+1|. Show (Xn) is Cauchy.
Thanks for any help.
I edited my mistake. Sorry again.
