The plan is to invest the money to provide monthly payments to help a small town build homes. The town will receive the first payment in a month and the payment will be $3000. Each month after that, the town will receive a payment that is 0.5% larger than the last payment. This pattern of payments will go on forever. Assume that the interest rate is 12% EAR. What is the value of the gift immediately after the first payment is made?

PLEASE show step by step based on the financial calculator. The answer is $671,672, but I am getting a different value.
