Question

Nathan has 80 stamps in his collection. he adds 1 stamp to it today. each day he plans to add twice 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?

Answer 1

Since he started with 80 stamps, your equation must include an 80. Also, because the number of stamps doubles each day, we can write that part of the equation as 2^x.

y=80+2^x
