$27 {(0.1)}^{n - 1}$

Step 1

Substitute in the value of $n$ to find the $n$ th term.

$a_{3} = 27 {(0.1)}^{(3) - 1}$

Step 2

Subtract $1$ from $3$ .

$a_{3} = 27 \cdot {0.1}^{2}$

Step 3

Raise $0.1$ to the power of $2$ .

$a_{3} = 27 \cdot 0.01$

Step 4

Multiply $27$ by $0.01$ .

$a_{3} = 0.27$
