Help! I've been asked to decide whether or not the given sequence is i) bounded above ii) bounded below iii) bounded and to determine (where appropriate) the supremum and infimum. I've got like 6 similar questions to attempt but I don't know where to start The examples we have been given in our notes are so complicated that I don't understand them Can someone show me how to approach the answer? Thanks very much! I know Supremum is the least upper bound and infimum is the greatest lower bound. http://tinypic.com/ftlrg5.jpg"
