Question

Identify the sequence graphed below and the average rate of change from n = 1 to n = 3.

Answer 1

an = 20(one half)n − 1; average rate of change is fifteen halves

an = 10(one half)n − 1; average rate of change is fifteen halves

an = 20(one half)n − 1; average rate of change is negative fifteen halves

an = 10(one half)n − 1; average rate of change is negative fifteen halves
