Answer:
True.
Step-by-step explanation:
In this case, you are subtracting 5 each time to get from one term to another. The definition of a arithmetic sequence is that the difference between any given numbers that are next to each other of the sequence have the same change.
For example:
-11 - (-6) = -5
-16 - (-11) = -5
-21 - (-16) = -5
Note that the change has been consistently -5.
