Which set of letters, when placed in order in the blanks of the given letter series, completes it?
T _ X T _ X _ A X _ A _ T A X
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → AATTX
In a letter series with blanks, the letters that are given show a group that repeats. Here the group is TAX (3 letters), written again and again:
Group 1: TAX, so the blank here is A
Group 2: TAX, so the blank here is A
Group 3: TAX, so the blank here is T
Group 4: TAX, so the blanks here are T, X
Group 5: TAX, no blank here
The blanks, in order, are therefore A, A, T, T, X.
