Which set of letters, when placed in order in the blanks of the given letter series, completes it?
S _ W R _ T W _ S T _ R S T _ R
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → TSRWW
In a letter series with blanks, the letters that are given show a group that repeats. Here the group is STWR (4 letters), written again and again:
Group 1: STWR, so the blank here is T
Group 2: STWR, so the blanks here are S, R
Group 3: STWR, so the blank here is W
Group 4: STWR, so the blank here is W
The blanks, in order, are therefore T, S, R, W, W.
