Question

Identify the sequence graphed below and the average rate of change from n = 0 to n = 3.

coordinate plane showing the point 2, 10, point 3, 5, point 4, 2.5, and point 5, 1.25

an = 8(one half)n − 2; average rate of change is −3
an = 10(one half)n − 2; average rate of change is negative thirty five thirds
an = 8(one half)n − 2; average rate of change is 3
an = 10(one half)n − 2; average rate of change is thirty five thirds
