1. Warm Up 09.06.11 Week 4 1) What is the distance between the sequence of numbers? -2, 4, 10, 16, 22,...

2. Geometry Sequences Day 1 I will identify arithmetic and geometric sequences. Arithmetic Sequence Add or subtract the same value to the previous term to get the next term. Ex 1 3, 8, 13, 18, 23, 28... + 5 Stating a Rule Use the words “starting with,” “previous,” and “next” in writing your rule Starting with three, five is added to the previous number to come up with the next number.

3. Ex 2 Figure 1Figure 2 Figure 3 Figure #Number of dots 11 25 39 413 517 Sequence? 1, 5, 9, 13, 17,... + 4 Starting with one, four is added to the previous number to come up with the next number. Rule?

4. Ex 3 225, 200, 175, 150,... Term #Term 1 225 2200 3175 4150 5125 Term #1Term #2Term #3 Term #4 Common difference? -25 Rule?Starting with 225, 25 is subtracted from the previous number to come up with the next number

5. Ex 4 Term #Term 1 2 26 310 414 518 2, 6, 10, 14,... Rule?Starting with 2, 4 is added to the previous number to come up with the next number

6. Do 1: Arithmetic Sequences 6, 16, 23, 37, 51,... 1, 5, 9, 13, 17,... 3, 6, 12, 24, 48,...

7. Geometric Sequence Multiply or divide the same value to the previous term to get the next term. Ex 67, 14, 28,56,112, 224,.. * 2 Term #Term 1 7 214 328 456 5112 Rule? Starting with 7, 2 is multiplied to the previous number to come up with the next number

8. Do: 2 Review What is an Arithmetic Sequence? Assignment: Handout 1.1 CW - Sequences 325, 310, 295, 280,... Term #Term Term #1Term #2Term #3 Term #4

9. Ex 5 Arithmetic Sequences 6, 17, 28, 39, 50,... 1, 5, 9, 14, 20,... 2, 6, 18, 54, 162,...
