A check processing center uses exponential smoothing to forecast the number of incoming checks each month. The number of checks received in June was $42$ million, while the forecast was $43$ million. A smoothing constant of $0\mathrm{.}25$ is used. Using exponential smoothing and given a$,$ the forecast for the month of july $=.$

If the check$-$processing center receive $46$ million checks in the month of July, then using the exponential smoothing and given a$,$ the forecast for the month of august $=$
