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