Thread: Sequences

Probably a silly question, but do all increasing sequences have a lower bound? I've been trying to work it out for a while and different people are telling me different things! Surely the lower bound will just be the first term, so when n=1? thanks in advance

If is an increasing sequence it means . Therefore is a lower bound.
