Select the letter pair that will replace the question mark (?) in the following series.
HM, EJ, BG, ?, VA
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → YD
In a letter-pair series the first and second letters each follow their own rule, checked through the place of each letter in the alphabet; going back from A continues from Z.
First letters H (8), E (5), B (2): each is 3 places back. Three places back from B is Y (B, A, Z, Y), and three back from Y (25) is V (22), the first letter of the last pair
Second letters M (13), J (10), G (7): also 3 places back, so the next is D (4), and three back from D is A, the last given letter
So the missing pair is YD.
