Question : Directions: In the following question, a series is given, with one term missing. Choose the correct alternative from the given ones that will complete the series.
XYZ, ABC, UVW, DEF, RST, GHI, ?
Option 1: UVW
Option 2: JKL
Option 3: OPQ
Option 4: NOP
Correct Answer: OPQ
Solution :
Given:
XYZ, ABC, UVW, DEF, RST, GHI, ?
In the above-given series, subtract 3 from the place value of each letter of the terms of odd places and add 3 to the place value of each letter of the given term at even places.
Odd places terms –
XYZ→X – 3 = U; Y – 3 = V; Z – 3 = W
UVW→U – 3 = R; V – 3 = S; W – 3 = T
RST→R – 3 = O; S – 3 = P; T – 3 = Q
Even places terms –
ABC→A + 3 = D; B + 3 = E; C + 3 = F
DEF→D + 3 = G; E + 3 = H; F + 3 = I
So, the missing term is OPQ. Hence, the third option is correct.
