Set pattern (decreasing with growing step): “Given set: (81, 77, 69)” — choose the option whose gaps mirror −4, then −8.

Introduction / Context:The reference set decreases by −4, then −8. We need a set with the same ordered pair of differences (not merely “decreasing”).

Given Data / Assumptions:

• 77 − 81 = −4; 69 − 77 = −8.

Concept / Approach:Compare each choice to find (−4, −8).

Step-by-Step Solution:(56, 52, 44): 52 − 56 = −4; 44 − 52 = −8 → matches exactly.

Why Other Options Are Wrong:They either use different gap sizes or a single constant gap.

Final Answer:(56, 52, 44)
