5. Using Recursive Rules with Sequences

Continue to next subchapter

Exercise 19 Page 447

Pay close attention to how the consecutive terms are related.

$a_{1} = 1,$ $a_{2} = 4,$ $a_{n} = a_{n - 2} + a_{n - 1}$

Practice makes perfect

We want to write a recursive rule for the given sequence. To do that, we first need to identify whether the given sequence is arithmetic, geometric, or neither. To do so we will calculate the difference and ratio between consecutive terms.
