A recursive rule for a geometric sequence is
LuckyWell [14K]

Answer:

C. a_n=(9)(\frac{2}{3})^{n-1}

Step-by-step explanation:

Iterative geometric sequence:

a_n=a_1x^{n-1}

Recursive geometric sequence:

a_n=xa_{n-1}

The equations are very similar and you only really need to rearrange it. The factor (2/3) and the first term (9) are given, so you can write the iterative equation:

a_n=(9)(\frac{2}{3})^{n-1}

And so the answer is C.

kozerog [31]

Answer:

It won't allow me to put in a link for the graph but on a graph it would of course be at -2 on the x-axis, but you would go only 3/4 the way to one so it'll be right under 1 on the y-axis
