S=n(n+1)/2 formula

S=n(n+1)/2 formula-When n = 1 the left side has only one term, 2 n1 = 2 11 = 2 0 = 1 The right side is 2 n 1= 2 1 1 = 1 Thus the statement is true for n = 1 The second step is the inductive step You need to show that if the statement is true for any particular value of n it is also true for the next value of n If you can do this then, since it is true= 1×2×3×4××n For n=0, 0!
