The next three terms are 60, 69, and 78.

Step-by-step explanation:

Well, let's take a look. The sequence is 15, 24, 33, 42, 51, __, __, __. Let's start by finding the common difference.

24-15 = 9.

33-24 = 9.

42-33 = 9.

51-42 = 9.

Therefore, the common difference of this arithmetic sequence, as you stated before, is nine. Thus, the difference in between EVERY single term onwards will be 9. In an arithmetic sequence, the common difference stays constant. You might learn later while working with finite differences that every term may not have the same difference, but worry about that later.

51+9 = 60.

60+9 = 69.

69+9 = 78.

The next three terms are 60, 69, and 78.

Hope this helps, have a great day.
