Which group of letters will come next in the given series?
CIG, FLJ, IOM, ?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → LRP
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 C (3), F (6), I (9): each is 3 places ahead, so next is \(9+3=12\), which is L
Middle letters I (9), L (12), O (15): each is 3 places ahead, so next is \(15+3=18\), which is R
Last letters G (7), J (10), M (13): each is 3 places ahead, so next is \(13+3=16\), which is P
So the next group is LRP.
