A culture of bacteria doubles every hour. If the culture begins with 57 bacteria, what is the explicit geometric formula for the growth of the culture?
Determine whether the pattern is an arithmetic or geometric sequence, and state the corresponding common difference or common ratio.
800, 400, 200, 100, ...
arithmetic, d = -400
arithmetic, r = -400
geometric, d = 1/2
geometric, r = 1/2
