Complete the following series.
GXB, JVD, MTF, PRH, ?
Show answer & explanation
Correct answer: D
Explanation
The pattern followed by the letters at each position is:
• First letter: Adds 3 to the alphabetical position:
G (7) + 3 = J (10), J (10) + 3 = M (13), M (13) + 3 = P (16), P (16) + 3 = S (19)
• Second letter: Subtracts 2 from the alphabetical position:
X (24) − 2 = V (22), V (22) − 2 = T (20), T (20) − 2 = R (18), R (18) − 2 = P (16)
• Third letter: Adds 2 to the alphabetical position:
B (2) + 2 = D (4), D (4) + 2 = F (6), F (6) + 2 = H (8), H (8) + 2 = J (10)
Therefore, the missing term is SPJ.
