#### Explanation:

The sequence goes up in 3s. The sequence we are really familiar with is the 3times table ....3,6,9,12 etc

3x1, 3x2, 3x3...

This sequence just needs adjusting by adding 2 to each term.

3x1+2, 3x2+2, 3x3+2 etc 3r+2

Or for the recurrence relationship we look at how we get from one term to the next. In this case add 3 each time. And of course we need to state which the first term is.
