தொடரில் உள்ள விடுபட்ட (?) ஐக் கண்டுபிடி BCA, FGE, ?, NOM, RSQ, VWU A. IJH B. KLJ C. KJI D. JKI

Each term uses three consecutive letters, written in the order 2nd, 3rd, 1st: ABC → BCA, EFG → FGE, MNO → NOM, QRS → RSQ, UVW → VWU. The groups start at A, E, I, M, Q, U (every fourth letter), so the missing group is IJK, written as JKI.
