In this section we will learn about finding the common difference, finding the next few terms of the sequences, and finding the formula for the $n$th term.

Look at the terms and see how much they are increasing or decreasing from one term to another.

Add the term with the common difference

__Common difference (term to term rule)__Look at the terms and see how much they are increasing or decreasing from one term to another.

__Finding the next term__Add the term with the common difference

__Finding the $n$th term (position to term rule)__- Find the common difference
- Write a multiplication table for the common difference. Find the general term for it
- Find the difference of the two sequences. Add/Subtract the difference to the general term to get the nth term.
