WebThe nth triangle number is the number of dots composing a triangle with n dots on a side, and is equal to the sum of the n natural numbers from 1 to n. where n is a natural number. This sum is Tn = n * (n + 1) / 2. This is the triangular number formula to find the nth … Web(b) Using your formula find the number of dots in the 60th term. Question: 8.

Webcontinues, how many dots will be in Figure 10? In this pattern, Figure 1 has one dot, Figure 2 has four dots and Figure 3 has nine dots. Notice that the number of dots in each is a series of squares, 12 = 1, 22 = 4 and 32 = 9. This means that figure 10 will have 102 = 100 dots. … WebIn the slope formula, (y2-y1)/ (x2-x1), The 2 is the y2 and the 1 is the y1. And, naturally, the 5 is the x2 and the 1 is the x1.
