arithmetic sequence is by adding or subtracting the same amount each time.
An arithmetic sequence is a sequence in which the difference between any two consecutive terms is the same, i.e., the difference is a constant.
A. from -2 to4 we have a difference of 6
from 4 to -6 we have a difference of 10
B. from -8 to -6 we have a difference of 2
from -6 to -4 also 2
C. from 2 to 4 is 2
from 4 to 8 is 4
