<p>aeln2007-- how can you find the sum of the first 1000 odd numbers on the ti-89? u can pm me if u want</p>
<p>i forgot,but ill try and explain it even though ive forgotten
it'll sound really stupid</p>
<p>you go to mode, put it in the mode where you get "n" whenever you press the variable key (i think its like, sequential mode or something)</p>
<p>and then you would use the format under calculate, or something, the alternate of the list key</p>
<p>thenuse the format in the instruction book, cant remember</p>
<p>use the arithmatic sequence equation, figure it out, itd start like an = (n-1)3, maybe theres addition in there
and then youd put the start and end limits, though youdneed the number of terms</p>
<p>sorry i couldnt help more</p>
<p>like i said, my memory is foggy, but ive done things like this before</p>
