In the following question, a series is given with one term missing. Choose the correct term to complete the sequence.
AD, EI, JN, PS, ?
Show answer & explanation
Correct answer: B
Explanation
The pattern followed in the given series is:
First letter of each term:
• A (1) + 4 = E (5)
• E (5) + 5 = J (10)
• J (10) + 6 = P (16)
• P (16) + 7 = W (23)
Second letter of each term:
• D (4) + 5 = I (9)
• I (9) + 5 = N (14)
• N (14) + 5 = S (19)
• S (19) + 5 = X (24)
Thus, the missing term is WX.
