Nathan has 80 stamps in his collection. He adds one stamp to it today. Each day he plans to add twice as the number of stamps as the previous day. If he keeps adding stamps at this rate for n days, which recursive function represents the number of stamps. He has on any day in the future?

The recursive function is,...

A. Next=now + 2^n
B. Next=now + 2^(n-1)
C. Next=now - 2^n-1

Starting at

A. 80
B. 2^n
C. 80^n
