Web2. Below are models of the first four triangular numbers. P1 = 1, P2=5, P3 = 12, that is Pn is the total number of dots in the nth figure, including dots on the inside. Notice we use P for pentagon. P1 = 1, P2=1 green dot plus 4 blue dots, P3 = one green dot + four blue dots + 7 red dots. a. (10 pts.) Webas shown in figure 2. Figure 2: the figure illustrates the growth of a triangular number. From left to right: n = 2, n = 3, n = 4. Note that the total number of dots in each triangle, starting from the first row down to the nth, equals p 3(n). This general pattern holds for all pa(n). Polygonal numbers can also be
