Question : Directions: Which letter cluster will replace the question mark (?) to complete the given series?
XDNC, VGOE, (?), RMQI, PPRK
Option 1: TJRG
Option 2: TKPG
Option 3: TJPG
Option 4: TJQG
Correct Answer: TJPG
Solution :
Given:
XDNC, VGOE, (?), RMQI, PPRK
Subtract 2 from the first letter and add 3, 1, and 2 to the second, third, and fourth letter of each previous term to obtain the next term in the series –
XDNC→X – 2 = V; D + 3 = G; N + 1 = O; C + 2 = E
VGOE→V – 2 = T; G + 3 = J; O + 1 = P; E + 2 = G
TJPG→T – 2 = R; J + 3 = M; P + 1 = Q; G + 2 = I
RMQI→R – 2 = P; M + 3 = P; Q + 1 = R; I + 2 = K
So, TJPG is the missing term in the series. Hence, the third option is correct.
