The video tutorial by Professor Dave covers sequences and series, focusing on their convergence and divergence. It begins with an introduction to sequences, including arithmetic, geometric, and Fibonacci sequences, and explains how they can be expressed using formulas. The tutorial then delves into the concepts of convergent and divergent sequences, using examples to illustrate these ideas. It introduces series, explaining how they are formed by summing sequence terms, and discusses the conditions under which series can be convergent or divergent. The video also covers geometric series and the criteria for series convergence, providing techniques for assessing limits and using algebraic manipulation.

What is a sequence in mathematics?

• A random list of numbers
