Given the first term and ratio find the first four terms of a geometric sequence

The video tutorial explains how to find the first few terms of a geometric sequence using the formula a_n = a_1 * r^(n-1). It starts by introducing the formula and given values, then demonstrates the calculation of the second, third, and fourth terms step-by-step. The tutorial concludes with a recap of the process, ensuring understanding of the method used.
