3 Arithmetic Sequences An arithmetic sequence has a common difference between consecutive terms. The sum of the first n terms of an arithmetic series is: The nth term of an arithmetic sequence is given by: Notes Over 4.8

4 Arithmetic Sequences Decide whether the sequence is arithmetic. Notes Over 4.8

5 Arithmetic Sequences Write a rule for the nth term of the sequence and find a 15. Notes Over 4.8
