Question

Which of the following is an arithmetic sequence?

O A. 5, -5, 5, -5, ...
O B. 3, 0, -3, -6, ...
O C. 2, 3, 7, 1, ..
O D. 2, 4, 16, 32, ...

Answer 1

B

Explanation:

In an artihmetic sequence, there is a constant difference between two consecutive terms.

So for instance:

`-6 -(-3) = -3`

`-3 -0 = -3`

`0 - 3 = -3`

As you can see there is a difference of
`-3` from one term to the next

____________________________

You can also find the constant difference the other way around, for instance

`3-0=3`

`0-(-3) = 3`

`-3-(-6) = 3`

In this example, you can see that each term is
`3` higher than the previous term

I hope this helps!!
