5-77.

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 ✎

  1. t(n) = 4.5n − 8

    1. Write the first 4 terms for the sequence.

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

    3. Write a recursive equation for this sequence.

−3.5, 1, 5.5, 10

She would evaluate the equation for n = 15.

A recursive equation is built using t(n+1).

As you look at the first four terms (from part (a)), how is the next term calculated for each term?
