Difficulty: Easy
Correct Answer: None of these
Explanation:
Introduction / Context:
This completion problem relies on recognizing a pattern in successive differences, specifically perfect squares of even integers.
Given Data / Assumptions:
Concept / Approach:
Compute differences and check for square numbers: 8 − 4, 24 − 8, 60 − 24, …
Step-by-Step Solution:
Verification / Alternative check:
The even-square progression is uniquely neat and yields a self-consistent completion.
Why Other Options Are Wrong:
178, 96, 109, 141 do not preserve the even-square sequence; only 124 would, but it is not among the listed options.
Common Pitfalls:
Trying multiplicative rules; here, additive square steps are more natural.
Final Answer:
The correct missing value is 124, which is not present among the options; hence None of these.
