Formal Definition: When a pattern in a number sequence is added or subtracted by the same number every time. http://wiki.answers.com/Q/What_is_the_definition_of_a_linear_pattern
Comparison: The formal definition may be clearer on how a pattern repeats but fails to mention the number sequence will form a straight line when plotted on a graph.
How to help student learn the definition: To help students remember the definition I would ask them identify the root word for linear which is “line”. Having students complete a few sample questions and then come up with patterns on their own will help the student develop there own sense of the definition.
