Write down in terms of n an expression of the following sequences a) 12 10 8 6 4
b) 25 20 15 10 5

Use the formulas a = x 2 – y 2, b = 2xy, c = x 2 + y 2 to answer this question. one leg of a right triangle has length 11 and all sides are whole numbers. find the lengths of the other two sides. the other leg = a0 and the hypotenuse = a1
