Question

3, 3, 4.5, 9, 22.5, and 67.5 what is the difference in these numbers

Answer 1

3 x 1 = 3
3 x 1.5 = 4.5
4.5 x 2 = 9
9 x 2.5 = 22.5
22.5 x 3 = 67.5

Answer 2

Step-by-step explanation:

The given series follows certain pattern. In order to get the difference between these numbers, we need to find the logic behind the series.

The given series is : 3, 3, 4.5, 9, 22.5, 67.5

In the first and second term we can see that: First Term * 1 = Second term

Now, if we multiply second term by 1.5 then we will get 3rd term and so on.

3*1=3

3*1.5=4.5

4.5*2=9

9*2.5=22.5

22.5*3=67.5

Difference between 1st and second term = 0

Difference between 2nd and 3rd term = 1.5

Difference between 3rd and 4th term = 4.5

Difference between 4th and 5th term = 13.5

Difference between 5th and 6th term = 45
