Review of 2.1 before 2.2 Lesson 2.1 pg 99, 100 # 2- 18 Problems 3 – 10, you have to come up with the next two terms in the sequence using inductive reasoning 3) 1, 10, 100, 1000, ______, ______ 5) 7, 3, -1, -5, -9, _____ , ______

2.2 Finding the nth Term Example 1: 20, 27, 34, 41, ____, ____ Rule: Example 2 with table Function notation : f(n) = n – 5 Substitute in n = 6 f(6) = n – 5 Term: n 1 2 3 4 5 Function rule: n - 5 n 1 2 3 4 5 6 7 -2n + 5

Coming up with the Function Rule 20, 27, 34, 41, ____, ____ Step 1: n = 1 and we see it goes up by 7 Step 2: 7(1) = 20? Step 3: Write what is missing into the rule 7 n + ? = 20 Term # : n 1 2 3 4 5 Function rule: 20 27 34 41
