I need help dividing a line into unequal segments!

Here is my problem:
Given a line ABCD

Values I know:
AD, AB, CD
AB is greater than CD.
I need to divide BC into 33 segments.
Each segment will decrease in length from AB down to CD.
I know it won’t work if BC is divided up into too many or too few sections. I am confident that given my real world lengths there is enough space to work with.
I need to build a formula wherein I can input AD, AB, CD, and the number of divisions for BC. Then have it tell me the resulting lengths of the sections from B to C.
I have been using Excel to write out a lot of attempts at linear formulas but typically when all is said and done if I sum the results I get a total length greater than AD.

Thank you in advance.

I will try to post this to the correct sub forum. Sorry for putting it here first.
