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
