Step 1: Observe the pattern in the series
The terms consist of two letters, the first letter and the second letter:
- First letters: A, C, F, (?)
- Second letters: Z, X, U, (?)
Step 2: Analyze the first letters
- A → C → F
- The pattern shows an increasing shift by 2 in the alphabet: A → C (shift by 2) → F (shift by 3).
The next letter will be F + 4 = J.
Step 3: Analyze the second letters
- Z → X → U
- The sequence shows that each letter shifts backward by 2 positions: Z → X (shift by 2) → U (shift by 3).
The next letter will be U - 4 = Q.
Step 4: Final Answer
The next term should be JQ, where the first letter is J and the second letter is Q.
Final Answer: The correct answer is (b) JQ.
