What is the change between the pairs of consecutive terms?
Pattern: Previous term +2 Next Two Terms: 9 and 11
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 2.
1+2 →3+2 →5+2 →7
To find the next two terms in the sequence, we will extend this pattern twice.
1+2 →3+2 →5+2 →7+2 → 9+2 → 11
