In the following question, a letter-number series is given with one or more terms missing as shown by (?). Choose the missing term out of the given alternatives.
D4W, H9T, L16Q, P25N, ...?..
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → T36K
Each term has three parts, and each part follows its own rule (letters taken by their place in the alphabet):
First letter: D (4), H (8), L (12), P (16) — it moves 4 places forward, so the next is T (20)
Number: 4, 9, 16, 25 are \(2^{2},3^{2},4^{2},5^{2}\), so the next is \(6^{2}=36\)
Last letter: W (23), T (20), Q (17), N (14) — it moves 3 places back, so the next is K (11)
