In given of the following question a letter-number series is given with one or more terms missing as shown by (?). Choose the missing term out of the given alternative.
GBL, JFN, MJP, ...?....
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → PNR
Treat the three letters of each term separately. The first letters are G, J, M — positions 7, 10, 13, rising by 3, so the next is position 16, the letter P. The second letters are B, F, J — positions 2, 6, 10, rising by 4, giving position 14, the letter N.
The third letters are L, N, P — positions 12, 14, 16, rising by 2, giving position 18, the letter R. The missing term is therefore PNR.
