Exercise 2 Page 200

By observing the change that occurs between consecutive terms, we can describe the pattern of the arithmetic sequence. Here, we see that to get from a term to the next term we add 0.4. Therefore, the common difference of the sequence is 0.4. 0.2 + 0.4 ⟶ 0.6 + 0.4 ⟶ 1 + 0.4 ⟶ 1.4 To find the next three terms in the sequence, we will extend this pattern three times. 0.2 + 0.4 → 0.6 + 0.4 → 1 + 0.4 → 1.4+ 0.4 → 1.8+ 0.4 → 2.2+ 0.4 → 2.6
