Elaine deposited $50 into a bank account. Each month, the balance in the account increases by 0.25%. The amount of money in her bank account n months later is expressed by the sequence a n , where a n = 50(1.0025) n . Which of the following is a recursive definition for the same sequence?
A. a 1 = 50 a n+1 = 0.0025 a n
B. a 1 = 50 a n+1 = 1.0025 a n
C. a 1 = 50.125 a n+1 = 0.0025 a n
D. a 1 = 50.125 a n+1 = 1.0025 a n
