As you will learn in this topic, arithmetic sequences are ordered sets of numbers, or terms, which behave much like linear functions, with a domain restricted to the positive integers. One distinguishing characteristic of linear functions is a constant rate of change, expressed as the slope of the line determined by the function.

	In preparation for this topic, let’s practice creating a table of values for a few linear functions, using a domain restricted to positive integers. Click here to access the review.
	In the last topic, you learned about sequences, which are ordered sets of terms. Many sequences exhibit patterns, and you may use the patterns to determine future terms in the sequence. Click here to test your ability to work with sequences and recursion formulas.
