Arithmetic Sequences: Example: Geometric Sequences: Tell whether each sequence is an arithmetic or geometric sequence. 1. 3. 2. 4. A sequence formed by adding a fixed number to a term to find the next number (the fixed number is called the common difference) A sequence formed by multiplying a term in the sequence by a fixed number to find the next term (the fixed number is called the common ratio)

Find the common ratio in each sequence. 5. 7. 6. 8. Find the next three numbers. 9. 11. 10. 12.
