The sequence is arithmetic.

1. The first term is $$a_1=12$$.
2. The second term is $$a_2=6$$. The difference between the second and first term is:
   $$
   6 - 12 = -6.
   $$
3. The third term is $$a_3=0$$. The difference between the third and second term is:
   $$
   0 - 6 = -6.
   $$
4. The fourth term is $$a_4=-6$$. The difference between the fourth and third term is:
   $$
   -6 - 0 = -6.
   $$
5. Since the difference between consecutive terms is constant and equals $$-6$$, the sequence is arithmetic.
The sequence is arithmetic because the difference between consecutive terms is always $$-6$$.
