Set pattern (increasing gaps): “Given set: (6, 15, 28)” — select the option with the same gap pattern (+9, then +13).

Introduction / Context:
Trio patterns may involve unequal but structured gaps. For (6, 15, 28), the differences are +9 and +13. We must find a set with the same successive gap sizes (not necessarily the same starting value).

Given Data / Assumptions:

• 15 − 6 = 9; 28 − 15 = 13.

Concept / Approach:
Check each candidate’s successive differences for +9, then +13.

Step-by-Step Solution:
(60, 69, 82): 69 − 60 = 9; 82 − 69 = 13 → matches.Other options do not replicate the gap pair (9, 13).

Final Answer:
(60, 69, 82)
