What is the recursive formula and how do we use it

The video tutorial introduces sequences and subscript notation, explaining how to determine a rule for a sequence. It then transitions to recursive formulas, highlighting their differences from regular formulas. The tutorial demonstrates how to apply recursive formulas to find terms in a sequence, providing examples and clarifications to ensure understanding.
