WebThe first term of the natural number is a 1 = 1. The second term of the natural number is a 2 = 2. The common difference is d = 1. Total number of terms = n. We know that the sum of A.P is = n 2 2 a + n - 1 d. Therefore the sum of the first n natural number is. S n = n 2 2 · 1 + 1 · n - 1 = n n + 1 2. WebThey show how you can build a cube using 3 "3D-staircases", 3 "2D-staircases", n singles and an extra single. Their formula shows that in going from a cube of size n^3 to a cube of size (n+1)^3, the larger cube is made by adding 3 face-extensions of size nxnx1, 3 new outside edges of size 1x1xn, and a new corner of size 1x1x1.
