Question

14 21 42 ? 315 number series

Answer 1

Answer:

The missing number will be 105.

Explanation:

The logic behind the given series is given as-

1st number × 1.5 = 2nd number

2nd number × 2 = 3rd number

3rd number × 2.5 = 4th number and so on ( multiplied with a number by an increment of 0.5)

Hence, here we require the fourth number which is missing- the 3rd number is 42 so 42× 2.5 = 105.
