$$12+5n$$
You can see from the figures formed that no matter how many triangles there are, there is always two 6's, which together form 12. Now according to the amount of triangles there are 5's. With 1 triangle there is one 5, with two triangles there are two fives, and with three triangles there are three 5's. So the amount of 5's corresponds to the amount of triangles, represented by n.
