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

Answer:

B

Step-by-step 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!!
