The number of pounds of fertilizer in each bag.
Ration expressions cause excluded values wherever the denominator equals zero.
So, for any expression like

-5 is an excluded value if 
For example, the simplest one would be

In fact, if you try to evaluate this function at -5, you'd have

which is undefined, and thus you can't evaluate the function, and thus -5 is an excluded value.
The first 5 terms in an arithmetic sequence is 4,2,0,-2,-4
Explanation:
The general form of an arithmetic sequence is

where a denotes the first term of the sequence, d denotes the common difference.
Here a = 4 and d = -2
To determine the consecutive terms of the sequence, let us substitute the values for n.
To find the second term, substitute n = 2 in the formula 

Simplifying,

Similarly,
For n = 3,

For n = 4,

For n = 5,

Thus, the first 5 terms of the arithmetic sequence is 4,2,0,-2,-4
