I use both a TI-89 and a TI-84. I can graph the recursive sequence on the TI-89 but not in the 84. I must be entering the sequence wrong.

In the TI-89 it is entered as follows:

u1=1.015825 * u1(n-1)

ui 1= 4000

It is graphing properly on the TI-89

The TI-84

nMin =What do I enter here?

u(n) = I will enter my recursive equation here

u (nMin)What do I enter here?

Can anyone help?
