Set (4, 9, 18) — which set follows the same relationship? (A) (8, 14, 22) (B) (10, 15, 25) (C) (6, 12, 23) (D) (12, 17, 26)
A(8, 14, 22)
B(10, 15, 25)
C(6, 12, 23)
D(12, 17, 26)
Answer & Solution
Correct answer: D. (12, 17, 26)
1. Relationship in (4,9,18): 9 − 4 = 5; 18 − 9 = 9. Differences are 5 and 9 (not arithmetic, +4 pattern).
2. In (12, 17, 26): 17 − 12 = 5; 26 − 17 = 9. Same pattern.
3. Therefore option D matches.
