ANSWER
The next term is 6.
Step-by-step explanation
The given arithmetic sequence is -6,-3,0,3,
There is a constant difference of 3.
That is,
-3--6=-3+6=3
This means that, we need to add 3 to the previous terms to get the subsequent terms.
To get the next term after 3, we add 3 to obtain 3+3=6
Therefore the next term of the sequence is 6.
