The consecutive letters in all the terms follow the pattern :
1st letter : P (-2 letters) = N (-2 letters) = L (-2 letters) = J (-2 letters) = H
2nd letter : R (-2 letters) = P (-2 letters) = N (-2 letters) = L (-2 letters) = J
3rd letter : Q (-2 letters) = O (-2 letters) = M (-2 letters) = K (-2 letters) = I
Thus, missing term = JLK
