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

           TRUE

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.

Period is the time it takes for one “cycle” to complete. in the parent sine function, period is 2*pi since sin(0) = 0, sin(pi/2) = 1, sin(pi) = 0, sin(3pi/2) = -1, and sin(2pi) = 0. at that point, the sequence repeats itself. i’m not sure if your graph is similar to the sine function since you didn’t provide a picture, but you can find the period by looking at a graph.
