\nNotice that in this second rule, the values of n are different they begin and end in different places and the constant 11 is different. The repeating element can be a number or even a shape. You can just as easily write F = {10, 20, 30, 40, 45, 35, 25, 15, 5}. The best way to approach this problem is to find all the squares of the numbers from 1 to 30 and then determine which are cubes: C = {1, 64, 729}. choose the logical answer to complete each sentence. You get these elements because 1 = 12 = 13, 64 = 82 = 43, and 729 = 272 = 93.
