Answer 1

Ryan opens a bank account with $50. Each month he deposits an amount that doubles his savings. Ryan gets $2 from the bank each month as an incentive for maintaining this savings pattern. Which recursive function represents the amount in Ryan’s account in any month? next = 2 × now + 2, starting at 50 next = 2 + 2, starting at 2 next = now + 2, starting at 50 next = 2 – now, starting at 50 next = 2 × now, starting at 2

Answer 2

50(2+2) i think this is right
