Chapter 12: Q 32. (page 809)

In Problems 29–36, the given pattern continues. Write down the nth term of a sequence $\{a_{n}\}$ suggested by the pattern.
$\frac{2}{3}, \frac{4}{9}, \frac{8}{27}, \frac{16}{81}, . . .$

Short Answer

Expert verified

The nth term of the given sequence is $a_{n} = {(\frac{2}{3})}^{n}$

Step by step solution

Step 1. Write the given information.

The given sequence is:

$\frac{2}{3}, \frac{4}{9}, \frac{8}{27}, \frac{16}{81}, . . .$

Step 2. Determine the pattern of the sequence and write down the nth term.

$a_{1} = \frac{2}{3}, a_{2} = \frac{4}{9}, a_{3} = \frac{8}{27}, a_{4} = \frac{16}{81}, . . .$

The pattern of the sequence is:

$a_{1} = {(\frac{2}{3})}^{1} = \frac{2}{3} a_{2} = {(\frac{2}{3})}^{2} = \frac{4}{9} a_{3} = {(\frac{2}{3})}^{3} = \frac{8}{27} a_{4} = {(\frac{2}{3})}^{4} = \frac{16}{81} a_{n} = {(\frac{2}{3})}^{n}$
