Question

Algebra 2 Honors:

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

A) an = 20(one half)n − 1; average rate of change is fifteen halves
B) an = 10(one half)n − 1; average rate of change is fifteen halves
C) an = 20(one half)n − 1; average rate of change is negative fifteen halves
D) an = 10(one half)n − 1; average rate of change is negative fifteen halves

Answer 1

one half?

Answer 2

Yes.

Answer 3

Answer 4

got kicked of a minute

Answer 5

\(2,10)\) is on the graph so it must be one that starts with
\[20\left(\frac{1}{2}\right)^{n-1}\]

Answer 6

and since the rate of change is clearly negative (it is going down) we don't even need to compute it, it must be C
that is the only one that fits

Answer 7

Okay. Thank you.

Answer 8

Also I have another one. Is there any way you could check my answer?
