A series is given with one term missing. Select the correct alternative from the given ones that will complete the series.
YRST, WPQR, UNOP, SLMN, ?

Series : YRST, WPQR, UNOP, SLMN, ?

The pattern followed in each letter of the terms is :

1st letter : Y (-2 letters) = W (-2 letters) = U (-2 letters) = S (-2 letters) = Q

2nd letter : R (-2 letters) = P (-2 letters) = N (-2 letters) = L (-2 letters) = J

3rd letter : S (-2 letters) = Q (-2 letters) = O (-2 letters) = M (-2 letters) = K

4th letter : T (-2 letters) = R (-2 letters) = P (-2 letters) = N (-2 letters) = L

Thus, missing term = QJKL
