Answer:
The sequence continually decreases.
Step-by-step explanation:
It has gone from:
12    to    9   to   6    to   3     
  |_____| |____|  |_____|
      -3          -3          -3
The pattern here is that the sequence is continually decreasing by 3.
So the continued pattern would be:
12, 9, 6, 3, 0
If you wanted to go to the negatives:
0, -3, -6, -9, -12, and so on.
I hope this helps!
