Question

Choose the missing term out of the given alternatives:
C4X, F9U, I16R, ?

• A. K25P
• B. L25P
• C. L250
• D. L27P

Hint:

Watch out for number-letter confusion like "O" being mistyped as "0".

Answer 1

The Correct Option is C

Step 1: Break each term into components: Letter + Number + Letter Term 1: C4X Term 2: F9U Term 3: I16R First letter pattern: C (3), F (6), I (9) — increasing by 3 ⇒ Next: L (12) Middle number pattern: 4, 9, 16 — perfect squares: \(2^2, 3^2, 4^2\) ⇒ Next: \(5^2 = 25\) Last letter pattern: X (24), U (21), R (18) — decreasing by 3 ⇒ Next: O (15) So, expected term = L25O Now match with the given options: Only option (3) L250 has correct components if the “O” was mistyped as zero (0), which is common in OCR-scanned questions. Hence, correct answer: (3) L250
