Assume that you have a variable called count that will take on the values 1,2,3, 4 and so on. you are going to formulate expressions in terms of count that will yield different sequences. For example, to get the sequence 2, 4, 6, 8, 10, 12 ..., you would use the expression (2 * count). Fill in the following table, indicating an expression that will generate each sequence.
a. 30,20,10,0,10,20,...
b. 7,3,1,5,9,13,...
