Texas Instruments
Texas Instruments: Exploring Infinite Series
In this activity, students learn to identify geometric series. They determine if a sequence converges and also learn to calculate the sum of numbers in a geometric series.
Better Lesson
Better Lesson: Geometric Sequences and Series
Students will be able to make use of structure on their way to deriving a formula for the sum of a geometric series. They will also gain more experience in finding the nth term of a sequence/series. Includes short video. [1:15]
