- 1. Agenda Wednesday, Jan. 6 Homework 22 p. 270 # 2 - 42 evens, 46, 47, 53 - 55, 71, 73 Ch. 5 Quest tomorrow
- 6. Inductive Reasoning = draw a conclusion or conjecture based on patterns
- 8. Complete Check Understanding 1 on p. 268
- 10. Sequence = a number pattern Term = each number in a sequence Arithmetic Sequence = a sequence where a fixed number is added to each previous term. Common Difference = the fixed number Example -4, 4, 12, 20 +8 +8 +8 Common Difference of Sequence is 8
- 11. Find the common difference of each arithmetic sequence. a. 5, 2, -1, -4 b. 8, 11, 14, 17
- 12. The rule for an Arithmetic Sequence is: A( n ) = a + ( n - 1) d A(n ) = nth term a = first term n = term number d = common difference We can use this rule to find the value of any given term.
- 13. Example Find the first, fifth and tenth term of the sequence that has the rule A( n ) = 12 + ( n - 1)(-2) First term A(1) = 12 + (1 - 1)(-2) A(1) = 12 Fifth term A(5) = 12 + (5 - 1)(-2) A(5) = 12 + (4)(-2) A(5) = 12 + -8 = 4 Tenth term A(10) = 12 + (10 - 1)(-2) A(10) = 12 + (9)(-2) A(10) = 12 + -18 = -6
