Suppose that a Q$-$learning agent transitions selects action $a=0$ from state $s=42$ and transitions to state $s^{\text{'}}=17$ and earns a reward of $r=5\mathrm{.}2.$ Suppose that the

agent's current estimate of the state value function for the two states involve are $V_{}(17)=24\mathrm{.}5$ and $V_{}(42)=16\mathrm{.}3.$

The target value used in the $Q-$learning update formula is defined as follows: $Q_T=r+*V_{}(s^{\text{'}})$

Using a discount rate of $=0\mathrm{.}8,$ calculate the $Q-$learning target value for this transition. Provide an exact answer.
