For the x-values 1, 2, 3, and so on, the y-values of a function form an arithmetic sequence that decreases in value. what type of function is it?

Step-by-step explanation:

A decreasing linear function is a function which variables are linear, that is, they have an exponent 1. Also, their slope is always negative.

In this context, the slope refer to the ratio of change of one variable with respect to the other one, according to this ratio, we say if the function increases or decreases.

So, in the given problem we have for each x-value, there's an y-value that decreases, that relationship describe is a decreasing ration.

Just remember that a decreasing function are those which x-variable increase while the y-variable decreases.

Therefore, the type of function describe is a decreasing linear function.
