Explanation:

Let’s break down the given series: FCC, UFH, OIS, LLX, FOC, ?

- Let’s check each letter’s pattern:

- 1st Letters: F (6), U (21), O (15), L (12), F (6)

- Sequence: 6, 21, 15, 12, 6 ? possible letters looped or based on some backward/forward rule.

- 2nd Letters: C (3), F (6), I (9), L (12), O (15)

- Sequence increases by 3 each step: 3, 6, 9, 12, 15

- 3rd Letters: C (3), H (8), S (19), X (24), C (3)

- 3, 8 (+5), 19 (+11), 24 (+5), 3 (loop/reset or pattern)

- Now, fill the pattern for next term:

- 1st letter: After F (6), see sequence repeats after LLX (L=12), so after F, the next should be U (21).

- 2nd letter: After O (15), next is R (18)

- 3rd letter: After C (3), following the pattern, add +5 ? H (8)

- So, the answer is URH (Option 3).

- Option Analysis:

- Option 1 (TRF): Letters do not fit pattern.

- Option 2 (VSG): Sequence doesn't match letter positioning.

- Option 3 (URH): Follows the established pattern.

- Option 4 (WTH): Not matching the letter sequences.

Correct Answer: Option 3: URH
