  1. Sequences Vocab Sequence – is an ordered list of numbers Term- Each number is the sequences Arithmetic sequence???- each number in the term is found by _________ to the previous term Positions- teach term has a position 1st, 2nd, 3rd, 4th …

  2. How to describe the relationship between terms Example • Look at first and second terms. • Subtract first term from second term • How much are you adding to the previous term??? 8, 13, 18, 23… First term = 8 Second term = 13 13 - 8 5 Adding 5 to pervious term

  3. Finding the next three terms in the sequence Example • Find the last term of our sequence. • Fellow our description to find new last term • Repeat • Repeat 8, 13, 18, 23… Last term is 23 Adding 5 to pervious term 23 + 5 = 28 28 + 5 = 33 33 + 5 = 38

  4. 0.4, 0.6, 0.8, 1…

  5. 0, 13, 26, 39…

  6. a. 4, 7, 10, 13 b. 1.0, 1.3, 1.6, 1.9… c. 2.5, 3.0, 3.5…

  7. The greeting cards that Meredith makes are sold in boxes at a gift store. The first week, the store sold 5 boxes. Each week, the store sells five more boxes. The pattern continues. What algebraic expression can be used to find the total number of boxes sold at the end of the 100th week? What is the total?

  8. Revisiting our Rules • Look at first and second terms. • Subtract first term from second term • How much are you adding to the previous term??? • Find the last term of our sequence. • Fellow our description to find new last term • Repeat • Repeat
