C Correct answer
Explanation

The pattern is: subtract 5, then (difference × 2/4), (difference × 2/3), (difference × 2/2), (difference × 2/1). Checking: 635-5=630; difference 5, then 5×2/4=2.5 (not 9). Alternative view: differences are 5, 9, 25, 100, 334 - these don't form a clear pattern. If 496 were 292 (following subtract 5 then ×2/1 pattern), the series would be consistent. 496 breaks the emerging pattern.
