Q. Which word best describes this formula for the sequence ana_n?\newlinean=6an1+2an3+14n+3a_n = 6a_{n - 1} + 2a_{n - 3} + 14n + 3\newlineChoices:\newline(A) explicit\newline(B) recursive
  1. Examine the Formula: Look at the formula: an=6an1+2an3+14n+3a_n = 6a_{n-1} + 2a_{n-3} + 14n + 3. Does it use previous terms of the sequence? Yes, it uses an1a_{n-1} and an3a_{n-3}, which are earlier terms in the sequence.
  2. Dependency on Previous Terms: Since the formula for ana_n depends on previous terms of the sequence, it's not explicit.\newlineAn explicit formula would directly calculate ana_n from nn without needing previous terms.
  3. Recursive Formula: The formula is recursive because it defines each term using previous terms in the sequence.
