What is the change between pairs of consecutive terms?
Pattern: previous term + 3 Next Three Numbers: 12, 15, and 18
Practice makes perfect
By observing the change that occurs between each consecutive term, we can describe the pattern of the sequence. Here, we see that the common difference from one term to the next is adding 3.
3+3 →6+3 →9
To find the next three numbers in the sequence, we will extend this pattern three times.
3+3 →6+3 →9+3 → 12+3 → 15+3 → 18
