Understanding Sequences and Their Properties

The video tutorial introduces sequences, explaining their definition, notation, and terminology. It covers patterns and formulas, including special sequences like Fibonacci. The tutorial discusses sequence representation, convergence, divergence, and graphical representation. It concludes with creating expressions for sequence terms.

What is a sequence primarily defined as?

• Term

How can sequences be viewed in terms of functions?
