Select the option in which the numbers are related in the same way as are the numbers in the given set.
(15, 556, 331)
Answer & explanation
Correct answer: option 3
(15, 556, 331)
The logic followed here is:
152 = 225 and 556 - 331 = 225
225 = 225
Similarly
(9, 159, 78)
92 = 81 and 159 - 78 = 81
81 = 81
