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 th term.
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 th term (position to term rule)
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 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.
