Excel: Intermediate values based on starting, ending values and number of intermediate steps

#1
Hi: Let's assume my starting value is 100, ending value is 5000 and the number of steps is 250. How can I come up with the intermediate values based on different cumulative function distributional assumptions? For instance, for a linear function, I can come up with the following values for the intermediate values: (5000 - 100)/250. But for other types of functions, how can I come up with the intermediate values? Thank you very much!
