In the following question, four groups of three numbers are given. In each group, the second and third numbers are related to the first number by a Logic/Rule/Relation. Three are similar on the basis of the same Logic/Rule/Relation. Select the odd one out from the given alternatives.
- A(15, 24, 29)
- B(13, 22, 26)
- C(53, 62, 66)
- D(47, 56, 60)
Solution & Step-by-step Explanation
Let's investigate the difference pattern between elements in each group (n

Option A:
24−15=9
29−24=5
Pattern: (+9,+5)
Option B:
22−13=9
26−22=4
Pattern: (+9,+4)
Option C:
62−53=9
66−62=4
Pattern: (+9,+4)
Option D:
56−47=9
60−56=4
Pattern: (+9,+4)
Options B, C, and D follow the pattern (+9,+4), whereas option A follows (+9,+5). Thus, option A is the odd one out.
