1. The problem statement, all variables and given/known data Let t1=sqrt(2) Let t_(n+1)=sqrt(2+sqrt(t_n)) (it's a recursively defined series) What does it converge to? 2. Relevant equations 3. The attempt at a solution I calculated it out for some values andI get 1.8312 (approx), but I don't want to express it in decimals, and I want to know if there's a good way to do this.
