Entering Recursive formulas - TI-83 Plus SE
I found a guide on entering recursive formulas for the TI-83/83 PLUS and I can go into sequence mode (per the example in the book) and display values on the home screen or in a table.

However, if I enter a problem from the book or from sample tests, I get domain and memory errors. Does anyone know how to convert the formulas into a format that the calculator can understand?

Example problem:

RE: No, not with the TI-83, however it's very simple with the TI-89 Titanium. You can just use the Copy and Paste Buttons...I use it all of the time for Newton's Method:D

In general, no. But for this specific kind of problem you can type the following:
-2 [enter].......(Output is -2)
+ 8 [enter].....(Output is 6)
+ 8 [enter].....(Output is 14)
+ 8 [enter].....(Output is 22)
etc.

Hi,

it is possible to enter maximal three sequences into the TI83/TI84. The names of the sequences are u, v and w. You find these names at 2ND 7, 2ND 8 and 2ND 9.

1. Switch into the sequence mode
2. Switch to Y= editor and enter all necessary values. To write the name of the sequence don't use ALPHA 5 = U but as I've mentioned above use 2ND 7.
3. Switch to WINDOW and enter all necessary values
4. Switch to TABLE. There you'll find the wanted results.
