Select the option in which the numbers are related in the same way as are the numbers in the given set.
(9, 217, 8)
A.(4, 37, 3)✓ Correct
B.(3, 49, 2)
C.(2, 76, 5)
D.(5, 625, 6)
Explanation
The pattern: a³ + b³ = middle number. 9³+8³=729+512=1241≠217. Try (a-b)³: (9-8)³=1, not 217. Try a³-b³: 729-512=217 ✓. For (4,37,3): 4³-3³=64-27=37 ✓. So the answer is (a).
