Answer:
generally, the sum divided by the number of summands
Step-by-step explanation:
In math the term "mean" can have different meanings, depending on the context. It will generally refer to the arithmetic mean, if no additional qualifiers are given. The arithmetic mean is also called the average.

<h3>arithmetic mean</h3>
The arithmetic mean of a set of numbers is their sum, divided by the number of numbers. It is sometimes represented by the Greek letter μ or a variable with an overbar.
<h3>geometric mean</h3>
The geometric mean will be the n-th root of the product of n numbers.
<h3>harmonic mean</h3>
The harmonic mean is the reciprocal of the arithmetic mean of the reciprocals.
<h3>proportion</h3>
In a proportion written as ...
a/b = c/d
The two values closest to the middle of the expression (b and c) are called the "means". Those farthest away (a and d) are called the "extremes". It is said that ...
the product of the <em>means</em> is equal to the product of the <em>extremes</em>
We are given the series of <span>a1 = -5 a2 = 20 a3 = -80. In this case, we can see that this is a geometric sequence with a geometric ratio equal to 20/-5 = -80/ 20 or equal to 4. Hence, r is equal to 4, a1 is equal to -5.
The geometric sequence formula is an = a1*r^(n-1) = -5 * (-4)^ (n-1) where n is an integer. Answer is B.</span>
