Prediction of parking occupation by ARMA model

I am working on a mobility project where goal is to predict underground parking occupation. Find attached two jmp data tables; (1) Data table "Time series occupation parking space" with evolution of occupation with time and (2) data table "ARMA Predicted Occupation" with occupation predictions by a (4,4) ARMA model (R² = 0,99!).

In data table (1) there is a column "ARMA Predicted Occ" where I would like to report in the green labeled rows after a given occupation three consecutive forecasted predictions (time span = 45 minutes) using the prediction formula in data table 2. How can this be done? Another clarified secret I may have missed day before yesterday in Copenhagen ..thanks for help! Frank
