How to write the sum in sigma notation given a geometric sequence

The video tutorial explains how to write sum notation for a sequence, starting with identifying the first term and the common ratio. It guides through the process of finding the last term and solving for the number of terms (N) using logarithmic properties. The tutorial concludes with a demonstration of solving the sequence using both logarithmic and one-to-one properties.
