1. Unit 6: Sequences & Series
Sec 1: Arithmetic & Geometric Sequences
Homework: pg 663 #1-20
Learning Target: I will find the pattern in a sequence and determine if it is arithmetic, geometric or neither

2. Ex 1: Using a Pattern in Real Life
Answer: C

3. Define the Following (pg 659):

4. Ex 2: Identifying Arithmetic Sequences
Determine whether each sequence is Arithmetic:
5, -6, -17, -28,…
-4, 12, 28, 42, …
-6, 3, 12, 21,…

5. Ex 3: Identifying Geometric Sequence
Determine whether each sequence is geometric.
-2, 6, -18, 54, …
8, 16, 24, 32, …
-8, 2, -0.5, 0.125, …

6. Ex 4: Finding a Pattern
Find the pattern and give the next 4 terms. Tell if the sequence is arithmetic, geometric or neither.
16, 24, 36, 54, …
1, 4, 9, 16, …
23, 17, 11, 5, …

7. Stump Your Buddy:
Create your own sequence. When you are finished, exchange your sequence with a friend a find each other’s pattern.
You will:
Find the next 4 terms.
Determine if the sequence is arithmetic, geometric or neither.
