WebThat is how Mathematical Induction works. In the world of numbers we say: Step 1. Show it is true for first case, usually n=1; Step 2. Show that if n=k is true then n=k+1 is also true; … WebStep 1: Now with the help of the principle of induction in Maths, let us check the validity of the given statement P (n) for n=1. P (1)= ( [1 (1+1)]/2)2 = (2/2)2 = 12 =1 . This is true. Step 2: Now as the given statement is true for n=1, we shall move forward and try proving this for n=k, i.e., 13+23+33+⋯+k3= ( [k (k+1)]/2)2 .
