Which group of letters will come next in the given series?
GAH, IBJ, JCK, LDM, ?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → MEN
In a series of letter groups, each place in the group follows its own rule, so the first, middle and last letters are checked separately.
First letters G (7), I (9), J (10), L (12): steps \(+2,\ +1,\ +2\) in turn, so the next step is \(+1\): \(12+1=13\), which is M
Middle letters A, B, C, D: the next letter each time, so next is E
Last letters H (8), J (10), K (11), M (13): steps \(+2,\ +1,\ +2\) in turn, so the next step is \(+1\): \(13+1=14\), which is N
So the next group is MEN.
