Find the next term (?) in the following alpha-numeric series:
A-01, D-04, G-09, J-16, M-25, ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → P-36
Each term has a letter part and a number part, and each part follows its own rule.
Letters A (1), D (4), G (7), J (10), M (13): each is 3 places ahead in the alphabet, so the next letter is the 16th letter, P
Numbers 01, 04, 09, 16, 25 are the squares \(1^2, 2^2, 3^2, 4^2, 5^2\), so the next number is \(6^2=36\)
