Suppose that the water in a swimming pool initially has a chlorine content of 4 parts per million, and 15 percent of the chlorine dissipates each day. If no additional chlorine is
added, write the explicit formula for a sequence that gives the chlorine concentration at
the beginning of each day.
an = 0.15(4)n-1
an= 0.85(4)n-1
an= 4(0.85)n-1
an = 4(0.15)n-1
