Unformatted text preview: a is greater than 1, the graph is unbounded. Upon observation, as n gets larger, y n gets larger. 16. y n = 2 + 1(-.7) n Since a is negative, the graph oscillates. Since the absolute value of a is less than 1, the graph is attracted to the value b/1-a. As n gets larger, y n approaches 2. 34. The terms approach 10 (which is b /1-a ). These terms are oscillating ( a is negative) and attracted to b /1-a (absolute value of a is less than 1)....
