Select the combination of letters that, when placed in the blanks of the given letter series in order, will complete the series.
c _ d _ e _ b _ c b _ e e d _ c _ b d _ e d _ c
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → bedcdbceb
In a letter series with blanks, look for a block of letters that repeats; the blanks are then the letters the block needs at those places. The 24 places split into three blocks of eight. The second block, c b _ e e d _ c, shows most of the block: c b d e e d b c, which reads the same both ways.
Block 1: c _ d _ e _ b _ needs b, e, d, c
Block 2: c b _ e e d _ c needs d, b
Block 3: _ b d _ e d _ c needs c, e, b
The series is cbdeedbc cbdeedbc cbdeedbc, and the blanks in order are bedcdbceb.
