A certain protected species normally doubles its population each month. The initial population is 20, but by the beginning of the next month, 1 specimen has died of an infection.  In successive months, the infection kills 2, then 4, then 8, and so forth. 1. Write a recurrence relation for the population at the beginning of month n. 2. Solve the recurrence relation. 3. What is the size of the population at the beginning of month 7?
