In this module you will review patterns and sequences
Module 2 - Lesson 1
Formula: an = a1 • r n-1
Formula: an = a1 + (n-1)d
Example: 2, 4, 6, 8...
Example: 1, 7, 49, 343, … is a geometric sequence that has a ratio of 7/1 between consecutive terms; each term after the first term can be found by multiplying the previous term by a constant, in this case the number 7 or 7/1
Example: 1, 7, 13, 19, … is an arithmetic sequence as it has a constant difference of +6 (i.e., 6 is added over and over)
Geometric Sequence - An ordered list of numbers that has the same ratio between consecutive terms.
Pattern - A set of numbers arranged in order (or in a sequence). The numbers and their arrangement are determined by a rule, including repetition and growth/decay rules.
Arithmetic Sequence - An ordered list of numbers that increases or decreases at a constant rate (i.e., the difference between numbers remains the same).
