Given the ratio and first term of a geometric sequence write the rule for nth term

The video tutorial explains how to write the rule for the NTH term of a geometric sequence. It covers identifying the first term (a sub 1) and the common ratio (R), and how to use these components in the formula to determine the NTH term. The tutorial provides a step-by-step guide to understanding and applying the formula effectively.
