Question 58

Find the missing set of letters in the following series
BAD , DAB , CAE , EAC ,_____

Solution

In the series, the even terms are the reflection of their corresponding previous odd term.

Considering the 1st and 3rd letters of the odd terms, we can see there's an increment of 1 letter. So, after B comes C and then D will come after C and so on.

The middle term is always A.

So the 5th term will be DAF.
