The mean is 15.25
12 + 24 + 8 + 17 = 61
Divide that by the total number of variables (4) to get 15.25.
Answer:

Step-by-step explanation:
<u>Alternating Sequences</u>
A sequence whose terms alternate in the sign is called an alternating sequence.
The given sequence consists of the numbers -6 and 6 in infinite alternation.
Such sequences can be expressed as equations of the form

Where a is the constant absolute value of each term and m is an expression adequately arranged to reproduce the alternation of signs.
Since the sign is minus for odd terms, and plus for even terms, m=n is a good expression for m. Thus:

Subtract 2x. (It would look like 4y=-2x+10
