Learn how to write a geometric sequence in summation notation

The video tutorial explains how to write a geometric sequence in summation notation. It begins by introducing the concept of summation notation and its components, including the initial term, upper limit, and NTH rule. The tutorial then guides viewers through determining the rule for the sequence and calculating the common ratio using specific terms. Finally, it demonstrates how to finalize the sequence in summation notation.
