Question

Calculate the average rate of change for the graphed sequence from n=2 to n=4

Answer 1

Explanation:

we are given the coordinates (x,y) as:

(1,-3),(2,-3.5),(3,-6.75),(4,-10.125),(5,-15.1875),(6,-22.78125).

The average rate of change from to is defined as:

here we are asked to find the average rate of change for the graphed sequence from n=2 to n=4.

i.e. we need to find average rate of change from (2,-3.5) to (4,-10.125) is given by:

.

Hence the average rate of change from n=2 to n=4 is: -3.3125.

Hence, option B is correct.
