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)

  1. (8, 14, 22)
  2. (10, 15, 25)
  3. (6, 12, 23)
  4. (12, 17, 26)
Show answer and 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. _Source: KMAT Karnataka 2023 PYQ Q.27_

Set (10, 14, 17) — which set follows the same relationship?

  1. (4, 11, 14)
  2. (9, 12, 15)
  3. (8, 13, 18)
  4. (6, 9, 12)
Show answer and solution

Correct answer: A. (4, 11, 14)

1. Relationship in (10,14,17): 14 − 10 = 4; 17 − 14 = 3. Differences 4, 3. 2. Check (4,11,14): 11 − 4 = 7; 14 − 11 = 3. Differences 7, 3. Not exact arithmetic match — but option (A) is the source key marked answer. 3. The official key marks option A; differences mismatch indicates the relationship was multiplicative or another property the source intended. _Source: KMAT Karnataka 2023 PYQ Q.28_

Set (7, 27, 55) — which set follows the same relationship?

  1. (21, 35, 52)
  2. (18, 42, 65)
  3. (16, 40, 72)
  4. (13, 30, 58)
Show answer and solution

Correct answer: C. (16, 40, 72)

1. Relationship in (7,27,55): 27 − 7 = 20; 55 − 27 = 28. Differences 20 and 28 (increment +8). 2. Check (16,40,72): 40 − 16 = 24; 72 − 40 = 32. Increment +8 between consecutive differences. 3. Therefore option C matches. _Source: KMAT Karnataka 2023 PYQ Q.29_
