1. Dr. Fowler AFM Unit 7-2 Arithmetic Sequences

3. Video – Sigma Notation: https://www.youtube.com/watch?v=KdD-HhmMcrc 8 minutes Pay close attention!!

4. An Arithmetic Sequence is defined as a sequence in which there is a common difference between consecutive terms.

5. Are the following sequences are arithmetic? If Yes, i dentify the common difference. YES YES YES NO NO

6. The general form of an ARITHMETIC sequence. First Term: Second Term: Third Term: Fourth Term: Fifth Term: nth Term:

7. Formula for the nth term of an ARITHMETIC sequence. I f w e k n o w a n y t h r e e o f t h e s e w e o u g h t t o b e a b l e t o f i n d t h e f o u r t h.

8. Given: Find: IDENTIFYSOLVE

9. Find the sum of the terms of this arithmetic series.

10. Find the sum of this series It is not convenient to find the last term.

11. Find the twenty fourth term of the arithmetic sequence: –3, 0, 3, 6,...
