Determine the sum of a finite geometric sequence

The video tutorial explains how to find the sum of a finite geometric sequence. It begins by identifying the necessary components: the first term, common ratio, and number of terms. The instructor then demonstrates how to apply the sum formula and simplifies the expression to arrive at the final sum. The tutorial concludes with a clear explanation of the calculation process.
