Induction proves a statement by using the previous case to imply the next one. Consider the following proof to demonstrate. We will show that for all positive integers n, 1 + 2+ + n = (n(n + 1))/ 2 First, we show it holds for n = 1. For n = 1, the above statement becomes (1+1)/2 = 1, which is true. Now, we will show that the previous result, for
