A-77.

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

$t(n)=4.5n-8$

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

Substitute $1, 2, 3,$ and $4$ for $n$. Record your answer as a sequence.

$−3.5, 1, 5.5, 10$

2. What would Avery do to write the $15^{\text{th}}$ term of this sequence?

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