Question

What is the common difference for this arithmetic sequence?

Answer 1

Answer:

B. -6

Step-by-step explanation:

The common difference here is the difference between each term. Since it is an arithmetic sequence the difference between each term will be the same value.

So, from 45 (the 1st term) to 39 (the 2nd term), the difference is -6

From 39(the 2nd term) to 33, the difference is also -6.

Therefore, we know that the common difference fro this arithmetic sequence is -6.

Hope this helps and ask me any question if it does not :)

Answer 2

Answer:

-6.

Step-by-step explanation:

39 - 45 = -6

33 - 39 = -6

27 - 33 = -6

21 - 27 = -6.
