Explanation

The differences are 168, 126, 90, 58, and follow the pattern: subtract consecutive multiples of 6 in reverse. 168 = 28 × 6, 126 = 21 × 6, 90 = 15 × 6, 58 = (approx) 9.67 × 6. More precisely: differences are 168, 126, 90, 58, and 58 - 34 = 24. The next difference is 34, so 62 - 34 = 28, not 24. Actually, checking pattern: 168-42=126, 126-36=90, 90-32=58, 58-34=24. The subtractions 42, 36, 32, 34 decrease then increase. Let me verify: 504-336=168, 336-210=126, 210-120=90, 120-62=58, 62-24=38. Differences are 168, 126, 90, 58, 38. Pattern: 168-42=126, 126-36=90, 90-32=58, 58-20=38. So 62-38=24, which matches option C.
