Answer
$\frac{1}{32}$
Work Step by Step
To calculate $a_n$, we plug in $n$ to the general formula.
To calculate the result, we use PEMDAS (parentheses, exponentation, multiplication, division, addition, subtraction) to determine which operation is applied first.
$a_{6} = \frac{6-4}{(-2)^{6}} = \frac{6-4}{64} = \frac{2}{64} = \frac{1}{32}$
