What should come in place of question mark (?) in the following series?
AYBZC, DWEXF, GUHVI, JSKTL, ?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → MQNRO
Each group of five letters is two series woven together: the 1st, 3rd and 5th letters run forward through the alphabet, and the 2nd and 4th letters form a second series.
1st, 3rd, 5th letters: ABC, DEF, GHI, JKL, so the next group has M, N, O
2nd, 4th letters: YZ, WX, UV, ST, each pair two letters back from the one before, so the next pair is Q, R
Weaving them together: M Q N R O
