Correct Answer: 14
Solution :
Given:
10, 4, 3, 3.5, 6, ?
The pattern is as follows –
(10 × 0.5) – 1 = 5 – 1 = 4;
(4 × 1) – 1 = 4 – 1 = 3;
(3 × 1.5) – 1 = 4.5 – 1 = 3.5;
(3.5 × 2) – 1 = 7 – 1 = 6;
(6 × 2.5) – 1 = 15 – 1 = 14
So, the missing number of the series is 14. Hence, the second option is correct.
