This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by $- \frac{1}{3}$ gives the next term. In other words, $a_{n} = a_{1} r^{n - 1}$ .

Geometric Sequence: $r = - \frac{1}{3}$

This is the form of a geometric sequence.

$a_{n} = a_{1} r^{n - 1}$

Substitute in the values of $a_{1} = - 32$ and $r = - \frac{1}{3}$ .

$a_{n} = - 32 {(- \frac{1}{3})}^{n - 1}$

Use the power rule ${(a b)}^{n} = a^{n} b^{n}$ to distribute the exponent.

Apply the product rule to $- \frac{1}{3}$ .

$a_{n} = - 32 ({(- 1)}^{n - 1} {(\frac{1}{3})}^{n - 1})$

Apply the product rule to $\frac{1}{3}$ .

$a_{n} = - 32 ({(- 1)}^{n - 1} \frac{1^{n - 1}}{3^{n - 1}})$

One to any power is one.

$a_{n} = - 32 ({(- 1)}^{n - 1} \frac{1}{3^{n - 1}})$

Combine ${(- 1)}^{n - 1}$ and $\frac{1}{3^{n - 1}}$ .

$a_{n} = - 32 \frac{{(- 1)}^{n - 1}}{3^{n - 1}}$

Combine $- 32$ and $\frac{{(- 1)}^{n - 1}}{3^{n - 1}}$ .

$a_{n} = \frac{- 32 {(- 1)}^{n - 1}}{3^{n - 1}}$

Move the negative in front of the fraction.

$a_{n} = - \frac{32 {(- 1)}^{n - 1}}{3^{n - 1}}$
