Lesson 3.11Concept: Arithmetic Sequences

EQ: How do we recognize and represent arithmetic sequences? F.BF.1-2 & F.LE.2

Vocabulary: Arithmetic Sequences, recursive formula, explicit formula, common difference13.10: Arithmetic Sequences23.10: Arithmetic Sequenceshttp://www.youtube.com/watch?v=kkGeOWYOFoA Nature by NumbersIntroductionAn arithmetic sequence is a list of terms separated by a common difference, d, which is the number added to each consecutive term in an arithmetic sequence.An arithmetic sequence is a linear function with a domain of whole numbers.

33.10: Arithmetic Sequences

Introduction (continued)Arithmetic sequences can be represented by formulas, either explicit or recursive.

A recursive formula is a formula used to find the next term of a sequence when the previous term is known.An explicit formula is a formula used to find the nth term of a sequence.

Find the first 5 terms of the sequence.Using the recursive formula: a1 = 29a2 = a1 + 5a2 = 29 + 5 = 34a3 = 34 + 5 = 39a4 = 39 + 5 = 44a5 = 44 + 5 = 49The first five terms of the sequence are 29, 34, 39, 44, and 49.
