The series is as follows:

$a_{n} = \{...,-45, a_{k},-12...\}$

So, we will analyze each term:

1. If $a_{k}=-28.5$ then:

$-28.5-(-45)=\frac{33}{2}$
$-12-(-28.5)=\frac{33}{2}$

2. If $a_{k}=-21$ then:

-21-(-45)=24

3. If $a_{k}=-19.5$ then:

$-19.5-(-45)=\frac{51}{2}$
$-12-(-19.5)=\frac{5}{2}$

3. If $a_{k}=-33$ then:

-33-(-45)=12

Finally, the sequence occurs when $a_{k}=-28.5$
This is the missing term
