Calculate the average rate of change for the graphed sequence from n = 2 to n = 6
Whoops this is the question... .0.

anonymous · Answer

oh.

anonymous · Answer

wait so is it still -4?

igreen · Answer

Average rate of change is slope.

Take any of the two points.

Let's take (1

igreen · Answer

Let's take (1, 17) and (2, 14).

Plug them into the slope formula:

$m = \dfrac{y_2-y_1}{x_2-x_1}$

$m = \dfrac{14-17}{2-1}$

Subtract:

$m = \dfrac{-3}{~~~1}$

Can you divide -3 / 1?
