This ones a bit of a trick question, since whether the integers are even or odd doesn't really matter. What does matter, is that consecutive odd integers are 2 numbers apart (as are consecutive even integers).
So again, if the first of the odd integers is the variable n
the consecutive odd integers after it can be written as:
n+2 , n+4, etc...
So the sum of four consecutive odd integers can be written as:
sum = n + (n+2) + (n+4) + (n+6)
Simplify:
sum = 4n + 12
And finally rearrange to solve for n:
= n
This can also be written as:
- 3 = n
Whichever way you prefer.

The area of the carpet is the amount of space it occupies
- The area of the carpet tile is 256 square inches
- The area covered by 120 tiles is 30720 squares inches
<h3>How to determine the carpet area</h3>
The dimension of the carpet tile is 16 inches by 16 inches
So, the area is:
Evaluate the product
Hence, the area of the carpet tile is 256 square inches
For 120 carpet tiles, the area is:
Hence, the area covered by 120 tiles is 30720 squares inches
