Find the next term in the alphanumeric series:B7A, F8F, J11K, N16P, ?

The correct answer is Option (1) → R23U

In a letter-number series, each part of the term follows its own rule, so the first letters, the numbers and the last letters are checked separately.

• First letters B (2), F (6), J (10), N (14):

  • Each is 4 places after the one before

  • So the next is \(14+4=18\), that is, R

• Numbers 7, 8, 11, 16:

  • The gaps are 1, 3, 5 (odd numbers)

  • So the next gap is 7: \(16+7=\) 23

• Last letters A (1), F (6), K (11), P (16):

  • Each is 5 places after the one before

  • So the next is \(16+5=21\), that is, U
