Find the equations of the asymptotes for each of the following functions. 

1. $−3, 1, 5, 9,13,17,21 …$ 

   Hint (a):

   What is the difference between each successive term?

2. $40, 20, 10, 5, …$ 

   Hint (b):

   Try division.

3.  $\frac { 1 } { 2 },\frac { 3 } { 2 } , \frac { 5 } { 2 } , \frac { 7 } { 2 } , \frac { 9 } { 2 } , ...$

   Partial Answer (c):

   Add $\frac{2}{2}$ to each successive term.
