Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Option B is correct. The pattern is cubes of consecutive natural numbers minus 4: 17³ - 4 = 4,913 - 4 = 4,909 (but 4,912 given). 16³ - 4 = 4,096 - 4 = 4,092 (but 4,098 given - WRONG). 15³ - 4 = 3,375 - 4 = 3,371 (but 3,372 given). 14³ - 4 = 2,744 - 4 = 2,740 (correct). 13³ - 4 = 2,197 - 4 = 2,193 (but 2,192 given). Actually, checking: 4,098 should be 4,092 to fit the pattern of (n³ - 4). Options A, C, D, and E are closer to the pattern or have consistent deviations.
