Explanations:

Note that for a sequence to be arithmetic, there must be a common difference, d.

3 - (-1) = 4

-9 - 3 = -12

27 - (-9) = 36

Since the differences between consecutive terms are not common, this is not an arithmetic sequence.

For 1, -2, -5, -8, -11....

-2-1 = -3

-5 -(-2) = -3

-8 - (-5) = -3

-11 - (-8) = -3

Since there is a common difference, d = -3, the sequence is an arithmetic sequence

For 26, 39, 52, 65, 78.....

39 - 26 = 13

52 - 39 = 13

65 - 52 = 13
