Yes, a starting number.  Thanks for helping me clarify what I'm after.  I
looking to calculate the value to be added in each step to get from 75 to
255 in a predetermined number of steps.

Unfortunately, this won't work as the goal is to end at a specified value
(in this case 255) and having the final step value equal to 1.  The number
of steps could change.

In other words, say I start with 75 and I know I want to have 30 steps
between 75 and 255 that get progressively smaller down to 1. How I determine
the value of each step?
