Answer to Question #6901 in Calculus for Tony Toyu

Question #6901

An artist wants to create a rough triangular design using uniform square tiles glued edge to edge. She places 'n' tiles in a row to form the base of the triangle and then makes each successive row tiles shorter that the preceding row. Find a formula for the number of tiles used in the design. (hint: Your answer will depend on whether 'n' is even or odd.)
