| April wants to use a discrete-time PID controller control her robot. She selects $200$ for the set point, sets all three gain parameters to $2$, and samples the state once per second (so that $\Delta t = 1$). When April executes this controller, the first three states are $205$, $204$, and $198$.

Compute the output of the controller after this third sensor reading. Show your work and mark your final answer clearly.
