Which of the following is an arithmetic sequence?
-2, 4, -6, 8,
-8, -6, -4, -2,
2, 4, 8, 16,

I think -8 -6 -4 -2 is an arithmetic sequence ( arithmetic sequence is a sequence of numbers such that the difference between the consecutive term is constant for example the sequence 5 7 9 11 13 15 is an arithmatic
with common difference of 2 )

The equation is y=17(7)+600 and it equals 717
