What will come in place of the question mark (?) in the following number series ?

Question 152

4, 6, 12, ?, 90, 315

Solution

Let the missing number be y

Now we can see that ,

6 = 4 x 1.5

12 = 6 x 2

y = 12 x 2.5 = 30

90 = 30 x 3

315 = 90 x 3.5

The given pattern is that the multiplying factor is increasing by 0.5 for every term when going from left to right.

Hence, answer is option C
