Correct Answer: 88
Solution :
Given:
(15, 5, 150) (16, 4, 128) (7, 7, 98) (11, 4, ?)
Multiply the first and the second numbers and then the resultant number by 2 to obtain the third number.
(15, 5, 150)→(15 × 5) × 2 = 75 × 2 = 150
(16, 4, 128)→(16 × 4) × 2 = 64 × 2 = 128
(7, 7, 98)→(7 × 7) × 2 = 49 × 2 = 98
Similarly, follow the same pattern for (11, 4, ?); (11 × 4) × 2 = 44 × 2 = 88
So, 88 is the missing term in the given set of numbers. Hence, the fourth option is correct.
