Find the odd letter group: RTW, QOM, IKG, BDF.
ARTW ✓ Correct
BQOM
CIKG
DBDF
Correct answer: (A) RTW — RTW is the odd letter group, so that is the answer.
Explanation
★RTW is the odd letter group, so that is the answer.
★In each group look at the step between successive letters.
★QOM steps by minus 2 each time, and BDF steps by plus 2 each time.
★IKG follows a steady step pattern as well.
★In RTW the steps are plus 2 and then plus 3, which is not constant.
★So the odd letter group is RTW.
