A moving average system is used for forecasting weekly demand. $${F_1}\left( t \right)$$ and $${F_2}\left( t \right)$$ are sequences of forecasts with parameters $${m_1}$$ and $${m_2}$$, respectively, where $${m_1}$$ and $${m_2}\left( {{m_1} > {m_2}} \right)$$ denote the numbers of weeks over which the moving averages are taken. The actual demand shows a step increase from $${d_1}$$ to $${d_2}$$ at a certain time. Subsequently,
A
neither $${F_1}\left( t \right)$$ nor $${F_2}\left( t \right)$$ will catch up with the value $${d_2}$$
B
both sequences $${F_1}\left( t \right)$$ and $${F_2}\left( t \right)$$ will reach $${d_2}$$ in the same period
C
$${F_1}\left( t \right)$$ will attain the value $${d_2}$$
D
$${F_2}\left( t \right)$$ will attain the value $${d_2}$$
