Using the recursive formula to find the first four terms of a sequence

The video tutorial explains how to use a recursive formula to find the first four terms of a sequence. It starts by introducing the concept and then demonstrates the calculation of the second and third terms. The tutorial concludes by recognizing the pattern in the sequence and summarizing the recursive approach.
