Is the answer 20?
That's how I got the answer.
The sequence number is already arranged in ascending order. So what I did is Separate the sequence number into 2 part.
First part is the first 5 digits while the second part is the last 5 digits. Then, choose the middle number in each of the 5 digits. Use the larger number to minus the smaller number.
40-20 =20
Answer:
Volume = 1114.1 
Step-by-step explanation:
Recall that the formula for the volume of a pyramid is given by:

where B is the area of the pyramid's base (in our case a square of side 12,8 in), and H the pyramid's height (in our case 20.4 in).
Then the square base of the pyramid has an area given by: 
Finally,we can now write the volume of the pyramid as:

Rounding the answer to a tenth of a cubic inch, we get:
Volume = 1114.1
