$A$ thermodynamic system undergoes a cyclic process through four stages. The energy values involved during this process are $Q_1 = 600 \ J, Q_2 = -400 \ J, Q_3 = -300 \ J$,and $Q_4 = 200 \ J$. The work values are $W_1 = 300 \ J, W_2 = -200 \ J, W_3 = -150 \ J$,and $W_4$. Find the value of $W_4$ in $J$.
