Find the odd one out.
In AZ, BY, and CX, the alphabet positions of the two letters add up to 27. D and U have positions 4 and 21, whose sum is 25.
Which letter group is different from the others?
In ACE, BDF, and CEG, the positions of consecutive letters increase by 2 each time. D and F differ by 2, but F and J differ by 4. Therefore, DFJ is different.
Select the odd letter group.
ABCD, EFGH, and IJKL each contain four consecutive alphabet letters. MNPR skips O and Q, so it is different.
Which pair is different from the others?
In AD, BE, and CF, the letters are separated by 3 alphabet positions. D and G are separated by 3 positions too, so all four pairs follow the same rule. This question has no odd option and is therefore intentionally replaced by the corrected question below.
Which letter pair is different from the others?
All four pairs follow the same rule: their letter positions add up to 27. Therefore, this question has no odd option and should not be used. The corrected question is the next one.
