How to determine a simple rule for a sequence

The video tutorial discusses subscript notation and how to determine a rule for a sequence. It begins with an introduction to subscript notation and explores initial values, particularly focusing on a sub 1. Various techniques are tested to find a rule, including multiplication and addition. The tutorial concludes by finalizing the rule as 4n - 1 and verifying its correctness for different values of n.
