Consider the arithmetic sequence: 6,2,-2,-6,... If n is an integer, which of these functions generate the sequence?
Choose all answers that apply:
a(n) = 10 – 4n for n > 0
b(n) = 10 – 4n for n > 1
c(n) = 18 - 4n for n > 2
d(n) = 14 - 4n for n > 3​

Step-by-step explanation:

Answer: the mean is 8 and the mean absolute deviation (mad) is 0.75.to find the mean, we simply add up all the values and divide by 8. we have: 64 / 8 = 8therefore, the mean is 8.now, we have to find the mad. we subtract all of the individual values from the mean and make them positive.the values will be {0 1 1 1 0 2 1 0} if you take the mean of those values you will have: 6 / 8 0 0.75the mad of the list is 0.75.
