Hello! I cannot figure out what's wrong with my Excel formula to solve for Annuity using PMT, I got the first one but I can't figure out why the rest are wrong.

\begin{tabular}{|c|c|r|r|c|} \hline NumberofPaymentsorYears & AnnualInterestRate & Future Value & Annuity & Present Value \\ \hline 3 & 10% & $0.00 & $8444.4 (Round to the nearest cent.) & $21,000.00 \\ \hline 21 & 4% & $21,000.00 & $656.88 (Round to the nearest cent.) & $0.00 \\ \hline 35 & 7% & $0.00 & $ (Round to the nearest cent.) & $220,000.00 \\ \hline \end{tabular}
