The sequence 1.5, 3.0, 4.5, 6.0, 7.5 is an example of an arithmetic sequence.

Explanation:

To identify an arithmetic sequence, check if the differences between consecutive terms are constant. Here's how to verify this:

For the sequence 1.5, 3.0, 4.5, 6.0, 7.5:

Difference between the second term (3.0) and the first term (1.5):

3.0 − 1.5 = 1.5

Difference between the third term (4.5) and the second term (3.0):

4.5 − 3.0 = 1.5

Difference between the fourth term (6.0) and the third term (4.5):

6.0 − 4.5 = 1.5

Difference between the fifth term (7.5) and the fourth term (6.0):

7.5 − 6.0 = 1.5
