Exercise 41 Page 319

Pay close attention to how the consecutive terms are related.

Recursive Rule: $a_{1} = 2, a_{2} = 4, a_{n} = a_{n - 1} - a_{n - 2}$ Next three terms: $2, 4$

Practice makes perfect

We want to write a recursive formula for the given sequence.

2, 4, 2, - 2, - 4, - 2, \dots

To do so we need to analyze how the consecutive terms are related. Let's find the difference between each pair of consecutive terms.
