Avery and Collin were trying to challenge each other with equations for sequences. Avery was looking at an explicit equation that Collin wrote.

$t(n) = 4.5n − 8$

1. Write the first $4$ terms for the sequence.

   Answer (a):

   $−3.5, 1, 5.5, 10$

2. What would Avery do to write the $15th$ term of this sequence?

   Answer (b):

   She would evaluate the equation for $n = 15$.

3. Write a recursive equation for this sequence.
