Suppose you are rehearsing for a concert. you plan to rehearse the piece you will perform four times the first day and then to double the number of times you rehearse the piece each day until the concert. what are two formulas you can write to describe the sequence of how many times you will rehearse the piece each day.* how can you write a sequence of numbers to represent this situation? *is the sequence arithmetic, geometric or neither? * how can you write explicit and recursive formulas for this sequence?
