the answer should be 6,

the total "power" (as I like to call it) is 4 x 18, which is 72.
You divide that by 12, giving you six.

Six pavers are needed.

Six pavers are needed, but we need to add only 6-4=2 pavers

Re @idk

4 * 18 = 12(4+n)
72 = 12(4+n)
-----------------
       12
6 -4 =4 - 4+n
6 - 4 = n
2 = n
