A Correct answer
Explanation

The pattern follows: 2→4 (×2), 4→8 (×2), 8→10 (+2), 10→5 (÷2), 5→11 (+6), 11→4 (÷2 approximately), 4→8 (×2). The sequence uses alternating operations: two doublings, then addition of 2, then halving, then adding 6. The final operation yields 4, which when doubled gives 8, confirming the cyclical pattern.
