Select the set in which the numbers are related in the same way as are the numbers of the following set.
(11, 13, 288)
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. (7, 11, 162)
Logic: (First term + Second term)2 / 2
(11, 13, 288)
(11 + 13)2 / 2
= 242 / 2
= 576 / 2 = 288
Check each option one by one:
(19, 23, 828)
(19 + 23)2 / 2
1764 / 2 = 882 is not equal to 828.
(3, 5, 31)
(3 + 5)2 / 2
64 / 2 = 32 is not equal to 31.
(7, 11, 162)
(7 + 11)2 / 2
324 / 2
162 = 162
We don't need to check further options.
Hence, the correct answer is (7, 11, 162).
