Using summation notation to express the sum of a geometric series

The video tutorial explains how to solve a problem involving a geometric series. It begins by introducing the series and the problem statement, followed by a detailed explanation of the geometric series formula. The instructor calculates the common ratio and verifies the first term. The tutorial then focuses on determining the final term and calculating the highest term in the series, using the formula and verifying calculations to ensure accuracy.
