Key learning points

1. The term-to-term rule is the common difference.
2. Finding the common difference can help when finding the n^th term rule.
3. Comparing the sequence to an appropriate multiplication table can help identify the translation that has been made.
4. The n^th term can be found for all arithmetic sequences.

Keywords
