I need a formula to slowly adjust one value to
another value over a known period. For example,
I have an increment value of 1 and I want that
value to decrease until it's 0 (or some other
value as needed, 0 for now). And I must reach
the known period (length in this case).

So I would be doing something like:

somelen = 62;
incval = 1;
someotherval = ?

for (x=0;x<somelen;x+=incval)
    {
    incval -= someotherval;
    if (incval <= 0)
        break;
    }

I need x to achieve "somelen" and "incval" to
achieve the value of 0 at about the same time,
give or take a bit.

How do I calculate "someotherval" ?
Thanks for your help.
