Is the following sequence arithmetic?
23, -7, -37, -67, ...
True
Or
False

Step-by-step explanation:

In arithmetic sequence the difference (d) between any pair of next and previous term is the same.

-7-23 = - 30

-37 - (-7) = -37+7 = - 30

-67 - (-37) = -67 +37 = - 30

d = -30

So this is  arithmetic sequence.
