A n. For example suppose the common ratio is 9. Sal shows how to evaluate a sequence that is defined with a recursive formula.
Taking a look at the examples again.
Explain in detail how you found both formulas. The recursive rule is a formula that states what term is given and what needs to be accomplished to the given term to determine the subsequent term. Mathematicians start counting at 1 so by convention n1 is the first term. Where n position of the term term number a n nth term the next term of the sequence.
