Chapter 8.1, Problem 84E

To determine

To graph: the first 10 terms of the sequence.

Explanation of Solution

Given information:

Given sequence

  $a_n=8{\left(-0.75\right)}^{n-1}$

Graph:

Use the table graphing utility to graph the first 10 terms of sequence.

Set the window $1\le n\le 10,-400\le x\le 400,-10\le y\le 10$

The terms are plotted as shown:

  

Interpretation:

The graph shows that the sequence has both positive and negative terms.
