Does the recursive sequence a1=1,an=an−1+1an−1 converge?
Since the function x+1/x is strictly monotonic increasing for all x>1, I don't think that the limit converges, but I'm not sure. Can anybody tell me whether the sequence is converging or not?
Answer
No. If it were convergent to some α, this value would verify
α=α+1α.
