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

Question 3

4, 32, 224, 1344, 6720, ?

Solution

Let the missing number be x

32÷4 = 8

224÷32 = 7

1344÷224 = 6

6720÷1344 = 5

As we can see that the division of consecutive numbers is forming a pattern of decreasing numbers by 1, so

x÷6720 = 4, it implies x is 26880
