In this ACT Math prep video, we get into the topic of geometric sequences and series. A geometric series occurs when numbers in a multiplication pattern are added together. When there are few terms in a geometric series to add up, it is easy to use a basic calculator. When you need to add up a lot of terms, a formula can to be used to quickly get the sum.
The example used in the video will be based off the following ACT math problem below:
