In the following question, various terms of an alphabet sequence are given with one or more terms missing as shown by (?). Choose the missing term.AZ, CX, FU,?

Correct answer: C. JQ

  • A. IR
  • B. IV
  • C. JQ
  • D. KP

Explanation

The sequence is based on the positions of the letters in the alphabet. For the first letters, the pattern is +2, +3, +4: A (1), C (3), F (6), leading to J (10). For the second letters, the pattern is -2, -3, -4: Z (26), X (24), U (21), leading to Q (17). Thus, the missing term is JQ.Other options do not match the calculated positions for both sequences: IR and IV would result in incorrect positions, and KP results in incorrect positions for both sequences as well.
