Which set of letters, when placed in order in the blanks of the given letter series, completes it?
Z _ Y Y X _ Z X Y _ X Z _ X Y _ X Z
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → XZYZY
In a letter series with blanks, the letters that are given show a group that repeats. Here the group is ZXYYXZ (6 letters), written again and again:
Group 1: ZXYYXZ, so the blanks here are X, Z
Group 2: ZXYYXZ, so the blank here is Y
Group 3: ZXYYXZ, so the blanks here are Z, Y
The blanks, in order, are therefore X, Z, Y, Z, Y.
