    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:

    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

    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.

    My Method:

    lilrhino here would be my method to get the 4th alliteration of this function. I do wouldn't think that it will work with a TI-83 ect. You must have a TI-89 or higher. But Anyways...

    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.
