In the following question, four groups of three numbers are given. In each group, the second and third number 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(157, 162, 167)
- B(138, 143, 148)
- C(222, 227, 232)
- D(167, 172, 187)
Solution & Step-by-step Explanation
Let us inspect the pattern of arithmetic differences across each triplets group:
Option A: 157
+5
162
+5
167
Option B: 138
+5
143
+5
148
Option C: 222
+5
227
+5
232
Option D: 167
+5
172
+15
187
Options A, B, and C follow a strictly uniform +5,+5 difference progression pattern. Option D deviates because its last step increments by +15.
