Can anyone help me solve this outstanding loan balance problem?

I solved for the payment and got $2,834.608468. Now how do I find the loan balance after the 10th payment?

Laura takes out a $50,000 loan for 15 years which she repays with annual payments at the end of each year. The annual interest rate is 1% for the first 2 years and then increases to 5% for the remainder of the loan. Laura's payments increase by 7% each year. Find the loan balance immediately following the 10th payment
