Future Value Of An Ordinary Annuity Calculator What Nominal Interest Rate Must The Analyst Be Using To Find The Future Value In This Problem?

What nominal interest rate must the analyst be using to find the future value in this problem? - future value of an ordinary annuity calculator

If an interest rate of zero percent, 10-year ordinary annuity has assessed a value of $ 4,000. If the future (compound) value of the pension estimated in year 10 is $ 6425, what rate nominal interest that the analyst should use to find the future value?

I see two ways to do this.

1) With the current price of $ 4000 on a zero interest rate, equal to the amount paid out the cash value of the number of periods (10) is divided. Thus, the payment amount 400th
Now that we are the payment amount can be plugged into the computer for the rest of the data:

FV = 6425
PMT = 400
N = 10
I / Y =?
Calculated: I / Y = 10.16296890% or 10.16%

or

2)
PV = 4000
FV = 6425
N = 10
I / Y =?
Computerized? I / Y = 4.85310944

Who (if any) is correct?
