Concept:The series alternates between a forward letter and its reverse counterpart (adding to 27). The forward letter increases by one each time.
Explanation:Start with D (4th letter) and number 4.
Next is W: 27 − 4 = 23, W is the 23rd letter.
Then E (5th letter) and number 5.
Next is V: 27 − 5 = 22, V is the 22nd letter.
Following the pattern, after V the next forward letter after E is F (6th letter) with number 6.
Thus, the next term is F6.
Answer:D. F6
