Question

Please Help!!

Is the given sequence arithmetic? If so identify the common difference.

0,-3,-6,-9,...

A. yes, -6

B. yes, -3

C. No

D. yes, 3

Answer 1

In the sequence of numbers, we see that each following number decreases by 3. This means that the answer is B. yes, -3.

Answer 2

Yeah it is!
Because there is no way it's being multiplied or divided. It could be, but it isn't being multiplied by the same number the whole time.
There is a common difference tho!
-3 - 0 is -3
So the answer is B
Hope this helps!
