There are no expressions visible and there is no figure n. It is, therefore, not possible to answer such a pointless question!

The expression that describes the total number of triangles in figure n is n(n+1)(n+2)/6. This can be derived using the formula for calculating the sum of the first n natural numbers, which is n(n+1)/2, and then multiplying it by (n+2)/3 to account for the different possible combinations of vertices in a triangle.
