(25 points) a) Sum the series 3 / 4 - 3 / 16 + 3 / 64 - 3 / 256 + .... b) A doctor wishes to give a patient a daily dose of D mgs of a certain medicine. The doctor knows that the body eliminates each day 60% of the amount present in the body. In the long run, the doctor would like the amount of drug in the body, after a dose is taken, to approach 6 mgs. What should D be? 2.
