between march and may

Explanation:

Step1: Calculate rate between Feb and Apr

Feb balance: $62, Apr balance: $56. Time: 2 months.
Rate of decrease: $\frac{62 - 56}{2} = \frac{6}{2} = 3$ dollars per month.

Step2: Calculate rate between Mar and May

Mar balance: $61, May balance: $57. Time: 2 months.
Rate of decrease: $\frac{61 - 57}{2} = \frac{4}{2} = 2$ dollars per month.

Step3: Compare the rates

3 > 2, so rate between Feb and Apr is greater.

Answer:

between February and April
