Least upper bound(lub) and greatest Lower bound(glb)

This video tries to illustrate examples on what least upper bound and greatest lower bound .Greatest lower bound is infemum while least upper bound is supremum .Due to the complexity of question , the question is divided in to two parts one with the even part and the other as odd part once this is done since the two parts are monotonic easily one can find the supremum and the infemum ,then once we have done it this way compare the glb of the two part and take the least which is the glb of the largest question .and also by comparing the supremum of the two parts and taking the largest of the two we can find the lub of the original question.

nice to see you, teacher, I would like you to make a video related to mathematical induction. Thank you!
