A linear sequence is a sequence that has a difference between the terms that is the same each time.

This means we can continue by using a term-to-term rule.

**Example: Find the 10 ^{th} number in this sequence.**

2, 6, 10, 14...

If we look at the differences, each term is 4 more than the next, so the term to term rule is +4.

If we continue the sequence we get 2, 6, 10, 14, 18, 22, 26, 30, 34, 38, 42, 46, 50

The tenth term is 38
