Which set of letters, when placed in order in the blanks of the given letter series, completes it?
A L _ _ U _ L L U U _ L _ _ U
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → LUAALU
In a letter series with blanks, the letters that are given show a group that repeats. Here the group is ALLUU (5 letters), written three times:
Copy 1: ALLUU, so the blanks here are L, U
Copy 2: ALLUU, so the blank here is A
Copy 3: ALLUU, so the blanks here are A, L, U
The blanks, in order, are therefore L, U, A, A, L, U.
