We need to find the Odd one out DEB FGD PQN TUS sequence of 3 letter words
The answer is TUS, since in the other groups, the 3rd and 1st letters are alternative letters, whereas the first 2 letters are successive letters of the alphabet.
Thus TUS is Odd one out
For DEB, B and D are alternate letters (with C in between) and D and E being consecutive letters;
For FGD, F and D are alternate letters (with E in between) and F and G being consecutive letters;
But for TUS, S and T are consecutive letters not alternate, although T and U are consecutive letters.
Hence, TUS is the odd man out.
So for the question to
Find the odd one out DEB FGD PQN TUS?
