Select the set in which the numbers are related in the same way as are the numbers of the following sets.

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding to/subtracting from/multiplying with 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

Explanation

• The core logic is an arithmetic progression with a common difference of 44.
• In the given sets, the second number is the first number plus 44, and the third number is the second number plus 44.
• The set (139, 183, 227) perfectly matches this pattern: 139 + 44 = 183, and 183 + 44 = 227.

Why Other Options Were Wrong

• Option A: The differences between consecutive numbers are not constant (54 and 34), so it does not match the required pattern.
• Option B: The differences between the numbers are inconsistent (24 and 44). The pattern requires a constant difference.
• Option D: This set has inconsistent differences between its numbers (50 and 34), failing to match the constant difference of 44 seen in the example sets.

Related Visual

• Visual 1: Flowchart: A simple flowchart showing the pattern: [First Number] -> (Add 44) -> [Second Number] -> (Add 44) -> [Third Number]. This visually reinforces the consistent operation.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Number Set Analogy as background academic context rather than a clinical decision trigger.
• This question tests logical reasoning and pattern recognition, which are foundational skills for problem-solving in any field, including nursing.
• While not a clinical question, the ability to identify patterns is crucial for nurses when assessing patient symptoms, interpreting lab trends, and recognizing deteriorating conditions.
• What if the pattern was multiplication? If the first set was (10, 20, 40), the pattern would be to multiply by 2. The approach would be the same: identify the rule (multiplication) and test the options against it.

How to Approach the Question

• First, analyze the relationship between the numbers in the given sets. Calculate the difference or ratio between consecutive numbers.
• In this case, calculate (133 - 89) and (177 - 133). You will find the difference is a constant +44.
• Verify this pattern with the second set: (146 - 102) and (190 - 146). The difference is again +44.
• Now that the pattern (add 44 to each number to get the next) is confirmed, systematically check each option.
• Apply the '+44' rule to each of the four options and select the one that follows the rule for both steps.
