A and C are not arithmetic because they are either dividing or adding. B does not have a pattern so D is the right answer. An arithmetic sequence is a sequence that has a pattern to it.  For example, 5, 7, 9, 11, 13, 15 ARE being added by 2.

This is the formula: an = d (n - 1) + c

I hope this helps. It is really easy when you can eliminate answers ;)

Answer: The answer is D. -1, 2, 5, 8

Step-by-step explanation: Arithmetic means Add or Subtract. You are adding 3 to get your next number. If that makes sense?

What is an equation of the line that passes through the points (-8, 2) and (-4, -3)?
denpristay [2]

Answer:

y = (-6/13)x + (4/13).,

Step-by-step explanation:

the equation of the line is:

y = mx + b, where "m" is the slope and "b" gives the y-intercept

m = (y2 - y1)/(x2 - x1)

m = (-2 - 4)/(5 - (-8))

m = -6/13

y = (-6/13)x + b

the line passes through the point (-8,4) means that for x = -8, y = 4

4 = (-6/13)(-8) + b

b = 4 - (-6/13)(-8)

b = 4/13

the equation of the line that passes through the points (-8,4) and (5,-2) is:

y = (-6/13)x + (4/13).
