Monday, May 11 Lesson Sequences

Objective: To describe the relationships and extend terms in arithmetic sequences.

Sequences A sequence is an ordered list of numbers.

Sequences A sequence is an ordered list of numbers. Each number in a sequence is a called a term.

Sequences A sequence is an ordered list of numbers. Each number in a sequence is a called a term. In an arithmetic sequence, each term is found by adding the same number to the previous term.

Sequences

In a sequence, each term has a specific position within the sequence. Consider the sequence 2, 4, 6, 8, …..

Sequences Notice that as the position number increases by 1, the value of the term increases by 2.

Sequences You can also write an algebraic expression to represent the relationship between any term in a sequence an its position in the sequence. What is the expression for this sequence?
