how would i determine the average rate (M/s) with this data

Part IV: Determining the rate law Complete the following table: Table 2 Table 3 \begin{tabular}{|l|c|c|c|} \hline \multirow{2}{*}{ Experiments } & \multicolumn{2}{|c|}{ Initial Concentrations } & Average Rate \\ \cline { 2 - 5 } & {[103} & {[M]} & \multicolumn{1}{c|}{(s)} \\ \hline Trials 1-3 & 0.00172M & 0.01375M & \\ \hline Trials 4-6 & 0.00344M & 0.01375M & \\ \hline Trials 7-9 & 0.00172m & 0.011001M & \\ \hline \end{tabular} Part IV: Determining the rate law Complete the following table: Table 2 Table 3 \begin{tabular}{|l|c|c|c|} \hline \multirow{2}{*}{ Experiments } & \multicolumn{2}{|c|}{ Initial Concentrations } & Average Rate \\ \cline { 2 - 5 } & {[103} & {[M]} & \multicolumn{1}{c|}{(s)} \\ \hline Trials 1-3 & 0.00172M & 0.01375M & \\ \hline Trials 4-6 & 0.00344M & 0.01375M & \\ \hline Trials 7-9 & 0.00172m & 0.011001M & \\ \hline \end{tabular}
