L25O

Correct Answer:

L25O

Explanation:

The correct answer is Option (4) → L25O

1. Analyze the First Letter (C, F, I, ...):

  • The position of C in the alphabet is 3.
  • The position of F in the alphabet is 6.
  • The position of I in the alphabet is 9.
  • Pattern: Each position increases by +3 ($3, 6, 9$).
  • Next Letter: The 12th position ($9 + 3$) corresponds to the letter L.

2. Analyze the Middle Number (4, 9, 16, ...):

  • $4 = 2^2$
  • $9 = 3^2$
  • $16 = 4^2$
  • Pattern: The numbers are squares of consecutive integers starting from 2.
  • Next Number: $5^2 = \mathbf{25}$.

3. Analyze the Last Letter (X, U, R, ...):

  • The position of X in the alphabet is 24.
  • The position of U in the alphabet is 21.
  • The position of R in the alphabet is 18.
  • Pattern: Each position decreases by -3 ($24, 21, 18$).
  • Next Letter: The 15th position ($18 - 3$) corresponds to the letter O.

Final Compilation:

By combining these three results (L, 25, and O), we get the final term: L25O
