Find a recursive rule for the nth term of the sequence.
-$$- 7 , - 42 , - 252 , - 1512 , \ldots$$
A) $a _ { n } = a _ { n - 1 } \cdot 12$
B) $a _ { n } = a _ { n - 1 } + 6$
C) $a _ { n } = a _ { n - 1 } + 12$
D) $a _ { n } = a _ { n - 1 } \cdot 6$

Each term in the sequence is obtained by multiplying the previous term by 6. For example, $-7 \times 6 = -42$, $-42 \times 6 = -252$, and so on.
