Q. Which word best describes this formula for the sequence ana_n?\newlinean=−3an−2−5an−3a_n = -3a_{n - 2} - 5a_{n - 3}\newlineChoices:\newline(A) explicit\newline(B) recursive
  1. Given Formula: The formula given is an=−3an−2−5an−3a_n = -3a_{n-2} - 5a_{n-3}.
  2. Definition of Formula: This formula defines ana_n in terms of previous terms an−2a_{n - 2} and an−3a_{n - 3}.
  3. Type of Formula: Since the formula defines a term based on its preceding terms, it's a recursive formula.
  4. Correct Choice: The correct choice that describes the formula is (B)(B) recursive.
