Excel formula to start at one number and arrive at another

Hello,

I have $380,000 in year 4 and $180,000 in year 1 how do I calculate the cells in between to reach that $380,000 number?

Thanks,
Max

How are you looking at making the jump from year 1 to year 4? a straight even increase?

are we talking year by year, month by month, week by week, day, by day?

how many cells are looking at?

perhaps you could upload a sample workbook with an example of what you're looking to achieve at the end?

Awesome, thank you so much!
