1. The first sequence is 2, 2.5, 3, 3.5, 4, 4.5. 2. To identify the type, check the difference between consecutive terms: $$2.5 - 2 = 0.5$$ $$3 - 2.5 = 0.5$$ $$3.5 - 3 = 0.5$$ $$4 - 3.5 = 0.5$$ $$4.5 - 4 = 0.5$$ 3. Since the difference is constant, this is an arithmetic sequence. 4. The answer for the first sequence is A. Arithmetic Sequence. 5. The second sequence is 1, 2, 3, 4, 5, 6, 7. 6. Check the difference between consecutive terms: $$2 - 1 = 1$$ $$3 - 2 = 1$$ $$4 - 3 = 1$$ $$5 - 4 = 1$$ $$6 - 5 = 1$$ $$7 - 6 = 1$$ 7. The difference is constant, so this is also an arithmetic sequence. 8. The answer for the second sequence is A. Arithmetic Sequence.
