Question

Is the given sequence arithmetic? If so, identify the common difference. −34, −28, −22, −16, . . .

yes, −6


yes, 6


yes, −4


no

Answer 1

yes, 6

Explanation:

The given sequence is −34, −28, −22, −16, . . .

We check to see if there is a constant difference among the terms.

`d=-28--34=-22--28=-16--22=6`

Since there is a constant difference of 6 among the consecutive terms, the sequence is arithmetic.

The correct choice is yes, 6
