The common difference is the difference between two consecutive terms in a sequence. To find it, we just need to do simple subtraction.

9−5=4
13−9=4
17−13=4
etc.

Each time, we get 4. There is a difference of 4 between each consecutive number in the sequence. Therefore, the common difference is 4.

Each term increases by 4
Something to do with the four times table
4 8 12 16
You have to add one o each term so the rule is 4n+1
