According to the circuit, shown in the attached picture,

Current through `R_4` = Current through `R_3` + Current through `R_5`

=0.18653-0.005=0.18153 A

So, `I_R_4` = 0.18153 A

Again, voltage through `R_5` =(current through `R_5` )*`R_5`

=-0.005*75=-0.375 V.

Thus, `V_R_5=-0.375 ` V.

Negative value of voltage means current flow will be in the opposite direction, which is indeed the case for R5.
