...writes this down like this: 1 + 2 + …+ n = ½ x n x (n+1) (Here n is bigger than or equal to 1) Let’s check if Gauss is right when n is 3. Is it true that 1 + 2 + 3 = ½ x 3 x 4? This is true, as 1 + 2 + 3 = 6 and ½ x 3 x 4 = 6. But working out if this formula holds for each and every number would be both dull and impossible, an enticing combination! We can prove...
