Option 2: (6, 36, 90)
Option 3: (8, 64, 160)
Option 4: (12, 144, 360)
Correct Answer: (4, 16, 48)
Solution :
Let's check the options –
First option:
(4, 16, 48); 4 × 4 = 16, 16 × 2.5 = 40
≠ 48
Second option:
(6, 36, 90); 6 × 6 = 36; 36 × 2.5 = 90
Third option:
(8, 64, 160); 8 × 8 = 64; 64 × 2.5 = 160
Fourth option:
(12, 144, 360); 12 × 12 = 144; 144 × 2.5 = 360
The first option does not fit the pattern. Hence, the first option is correct.
