Question

Which of the following is an arithmetic sequence? A. 2, 4, 8, 16, 32 B. 3, 6, 9, 15, 24 C. 2, 5, 7, 12, 19 D. 6, 13, 20, 27, 34

Answer 1

`D`

Explanation:

.

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

Option `D` is an arithmetic sequence because:

`13-6=7`

`20-13=7`

`27-20=7`

`34-27=7`

As you can see, each term is `7` higher than the previous term.
