Recursive formula is a formula that is used to determine the next term of a sequence using one or more of the preceding terms.
For the sequence 3, 12, 48, 192, â¦, ask students to: Find the next term. Write a recursive rule. Express each term with exponents. Give the recursive rule An= -5An â 1, where the first term is 3. Ask students to: Write out the first 4 terms in the sequence.
