It takes the high-speed train x hours to travel the z miles from town a to town b at a constant rate, while it takes the regular train y hours to travel the same distance at a constant rate. if the high-speed train leaves town a for town b at the same time that the regular train leaves town b for town a, how many more miles will the high-speed train have traveled than the regular train when the two trains pass each other? (a) z(y – x)/x + y(b) z(x – y)/x + y(c) z(x + y)/y – x(d) xy(x – y)/x + y(e) xy(y – x)/x + y

Use mathematical induction to prove the statement is true for all positive integers n, or show why it is false. 1^2 + 4^2 + 7^2 + + (3n - 2)^2 = [n(6n^2-3n-1)/2]
