Learn what a geometric sequence is and how to perform several related tasks: find the nth term, write the formula for the nth term, and calculate a finite geometric series. This tutorial offers definitions, example problems with...

Solve problems such as: The first four terms in a geometric sequence are 1/3, 1, 3, and 9. Find an explicit formula for the sequence. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video...

Find the recursive formula of a geometric sequence given the first few terms or given an explicit formula. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

This task presents a real world application, prescribing a course of antibiotics. In this task, a finite geometric series is utilized. Aligns with A-SSE.B.4.

In this activity, you can see a representation of several geometric series and their limits.

This tasks requires students to explore properties of the Cantor Set, which has many uncountable points, no intervals of real numbers, and has length of zero. Aligns with A-SSE.B.4.
