the following numbers are put in a machine and put out, they are in a pattern. if you put in 4.5, what will you get out.
input output
15 7
6 4
0 2
3 1
6 0
12 2

You have a linear relationship netween input and output. Note that every increase of 3 in the input increases the output by 1. 4.5 is 1.5 above 3, so you will 0.5 above 1, or 0.5.
If you were to use algebra, it would be
y = x/3 2
x is the input and y is the output 
find the out put 0 to 25 2 to 55 4 to 85
