Equilibrium Partial Pressure Calculation

Consider the following reaction at 298 K:
$2\text{NO}(g) + \text{O}_2(g) \rightleftharpoons 2\text{NO}_2(g)$, $K_p = 1.6 \times 10^{12}$
In an experiment, the initial partial pressures are $P_\text{NO} = 0.020$ atm, $P_{\text{O}_2} = 0.010$ atm, and $P_{\text{NO}_2} = 0.015$ atm. Which of the following is the best approximation of the partial pressure of $\text{NO}_2(g)$ at equilibrium?
