Question :
Directions: From among the given alternatives select the one in which the set of numbers is most like the set of numbers in the question.
(2, 10, 28)
Option 1: (4, 20, 56)
Option 2: (7, 42, 49)
Option 3: (12, 24, 48)
Option 4: (2, 27, 81)
Correct Answer: (4, 20, 56)
Solution :
Given:
(2, 10, 28)
(2, 10, 28)→2 × 5 = 10; 2 × 14 = 28
Let's check the option –
First option:
(4, 20, 56)→4 × 5 = 20; 4 × 14 = 56
Second option:
(7, 42, 49)→7 × 5 = 35 ≠ 42; 7 × 14 = 98 ≠ 49
Third option:
(12, 24, 48)→12 × 5 = 60 ≠ 24; 12 × 14 =168 ≠ 48
Fourth option:
(2, 27, 81)→2 × 5 = 10 ≠ 27; 2 × 14 = 28 ≠ 81
So, only the first option follows the same pattern as followed by the given set of numbers. Hence, the first option is correct.
