Select the letter Cluster that can replace the question mark (?) in the following series.
QKR, UOV, YSZ, CWD, ?
In each letter cluster +4 is done to obtain the next one.
QKR ==> (Q+4) (K+4)Â (R+4) ==>Â UOV
UOV ==>Â (U+4)Â (O+4)Â (V+4) ==>Â YSZ
YSZ ==>Â (Y+4)Â (S+4)Â (Z+4)Â ==>Â CWD
CWD ==>Â (C+4)Â (W+4)Â (D+4) ==> GAH
So 'GAH' will come in place of the question mark.
