seq question -again

hello everyone, I posted this a while ago, but no one responded, so i
thought I should give it another try because probably not everyone has
seen the earlier post.

If we have a recursion x_1=2, x_n=2^(x_n-1), how does one show that
the sequence x_n(mod m) stabilizes in Z/mZ for any m ?

Thanks
