Select the set in which the numbers are related in the same way as are the numbers of the following sets:
(145, 151, 137)
(122, 128, 114)

Appeared in: DSSSB 13 August 2024

Explanation

The relationship in the given sets is: (First Number + 6 = Second Number) and (Second Number - 14 = Third Number).
Let's check the first given set: (145, 151, 137). Here, 145 + 6 = 151, and 151 - 14 = 137.
Let's check the second given set: (122, 128, 114). Here, 122 + 6 = 128, and 128 - 14 = 114.
The correct option (111, 117, 103) perfectly follows this rule: 111 + 6 = 117, and 117 - 14 = 103.

Option A: In the set (95, 101, 89), the first part of the pattern holds true (95 + 6 = 101), but the second part fails. When 14 is subtracted from 101, the result is 87, not 89.
Option C: In the set (133, 139, 135), the first part of the pattern is correct (133 + 6 = 139), but the second part is not. Subtracting 14 from 139 gives 125, not 135.
Option D: In the set (86, 92, 68), the first part of the pattern is met (86 + 6 = 92), but the second part is incorrect. Subtracting 14 from 92 results in 78, not 68.

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.
While this is a general intelligence question, the underlying skill of pattern recognition is crucial in nursing.
Nurses must recognize trends and patterns in a patient's vital signs, lab results, or symptoms to identify improvement or deterioration.
For example, recognizing a pattern of gradually decreasing blood pressure and increasing heart rate can be an early sign of shock.

How to Approach the Question

First, carefully examine the numbers within each of the given sets, for example, (145, 151, 137).
Identify the mathematical operation that connects the first number to the second (145 to 151 is +6).
Next, identify the operation that connects the second number to the third (151 to 137 is -14).
Confirm this two-step rule (+6, then -14) works for the second given set (122, 128, 114).
Systematically apply this confirmed rule to each of the four options.
Select the option that successfully follows both steps of the rule.
