Question Analysis
This question involves identifying an arithmetic sequence with a negative common difference, including zero, and transitioning from positive to negative terms. The main focus is on verifying the constant negative difference.

Key Concept Explanation
An arithmetic sequence with a negative common difference will decrease by the same amount each time, and it can include zero and transition to negative terms while maintaining the constant difference.

Step-by-Step Solution
Calculate the differences:
3 - 6 = -3
0 - 3 = -3
-3 - 0 = -3
-6 - (-3) = -6 + 3 = -3
The difference between each consecutive pair of terms is a constant -3, so the sequen...
