    It has subsequence {1/n} therefore it has subsequence converges to zero i.e. one limit point is zero. But as it is unbounded implies whole s is not convergent therefore there doen't exists limit of a sequence

    s has subsequence ( 1,2,3 ... n) which is unbounded , so S is unbounded. see attached

    but in study material it is mention that limit is 0. which made me confused

    as S is unbounded , it can't have limit point , there maybe mistake in study material..

    but subsequence of S (1,1/2,1/3,...1/n ) is bounbed , it's have limit 0
