For example, 1 = 1², 1+3 = 4 = 2²,1+3+5 = 9 = 3², 1 + 3 + 5 + 7 = 16 = 4² and so on. Algebraically, this is written as: 1+3+5++ (2n - 1) = n² Geometrically, this can be visualized by arranging dots in the shape of a square. Start with a single dot for 12. Then, if you add 3 dots around it, you can form a 2 ×
