Arithmetic Sequence Objective: Learn to describe the relationships and extend the terms in arithmetic sequence.

A sequence is an ordered list of numbers A sequence is an ordered list of numbers. Each number in the sequence is called a term. An example of an arithmetic sequence is …. Sequence: 8, 11, 14, 17, 20, ____, _____, ______. Pattern: adding 3 In a sequence, each term (number) has a specific position within the sequence. Consider the sequence 2, 4, 6, 8, 10, …. What is the pattern: ______________________

Examples: Write the next three terms in each sequence and describe the pattern or relationship. 1) 0, 7, 14,21, ______, _______, _______. Pattern: ______________________ 2) 6, 16, 26, 36, _______, ________, _______. 3) 5, 10, 15, 20, ________, ________, _______. Pattern: _____________________

Homework: Complete the sequence, then say what is the pattern. 1. 1, 7, 13, 19, _______, ________,________. Pattern; _______________________________. 2. 26, 34, 42, 50, ______, ______, _______.
