What is a sequence

The video tutorial introduces the concepts of functions and sequences. It begins with a review of functions, explaining how to evaluate them using specific inputs. The tutorial then transitions to sequences, highlighting their similarities to functions but with distinct characteristics like terms and subscripts. The instructor demonstrates how to calculate sequence terms using a rule and identifies patterns within sequences. The video concludes with an explanation of finite and infinite sequences, setting the stage for further exploration of sequence relationships and rules.
