Correct Answer: JFD
Solution :
Given:
DRH, YOG, TLF, OIE, ?
Subtract 5, 3, and 1 from the place value of the first, second, and third letters of the previous letter cluster to obtain the next letter cluster of the series.
First letter
of the series→D – 5 = Y; Y – 5 = T; T – 5 = O; O – 5 = J
Second letter
of the series→R – 3 = O; O – 3 = L; L – 3 = I; I – 3 = F
Third letter
of the series→H – 1 = G; G – 1 = F; F – 1 = E; E – 1 = D
So, JFD is the missing letter cluster of the series. Hence, the first option is correct.
