Answer:
6%
Step-by-step explanation:
The computation of the maximum amount that the interest rate can reach is shown below:
Since the arm rate is increased from 2% to 3% at the first adjustment
Now at the second adjustment, it increased from 3% to 5%
At the third adjustment, it increased from 5% to 7%
So here the interest rate should be
= 2% + 4%
= 6%
Also it can never be more than 6%
