The video tutorial explores infinite geometric series, focusing on their fascinating properties and applications in calculus. It explains the concepts of convergence and divergence, highlighting how a series can have an upper bound despite having infinite terms. The tutorial demonstrates how to calculate the sum of a convergent series using a specific formula and provides examples of both convergent and divergent series. Additionally, it discusses Gabriel's Horn, a mathematical concept with an infinite surface area but finite volume, illustrating the intriguing nature of infinite series.

What is an infinite geometric series?

• A series with a common difference.
