The intercept term is $550$ and the first and second order moving average coefficients, omega$\_\{1\}$ and $1,$ are estimated as $0\mathrm{.}50$ and $-0\mathrm{.}40,$ respectively, in an ARIMA $(1,0,1)$ process. What would be the one$-$period ahead forecast of the variable of interest if the current and one period lagged values are given as $560$ and $425$ Or the forecast variable itself and as $40$ and$-75$ for the past forecast errors from the model
