What are the ^ supposed to mean multiplecation?
2x° + 1 + x° - 6 + 59°= 360°
3x° + 54° = 360°
3x = 306°
x = 102°
2(102°) + 1°= 204° + 1° = 205°
102° - 6°= 96°
205° + 96° + 59°= 360°
The mean is 8 gerbils and the MAD is 4.29.
<h3>What is the mean?</h3>
Mean is the average of a set of numbers. It is determined by adding the numbers together and dividing it by the total number
Mean = sum of the numbers / total number
(0 + 3 + 6 + 9 + 11 + 13 + 14) / 7 = 8
What is the MAD?
MAD = ∑ l x - m(x) l
| (0 - 8) + (3 - 8) + (6 - 8) + (9 - 8) + (11 - 8) + (13 - 8) + (14 - 8)| / 7 = 4.29

Answer:
Step-by-step explanation:
Notice that the series: 1 - 3 + 9 - 27 +... clearly has powers of the factor 3 in its terms and it is also an alternate series (the terms alternate from positive to negative). The terms are positive for 
(even terms) , while the odd terms 
are negative. (so most likely there should be a factor (-1) in the common ratio.
We can then represent it with the following summation expression:
given that each of its first four terms are:
Do me do me do me.............
