Present value is defined as K/i where K is the annual cash flow and i is the discount rate.

How would this formula change if the cash flow happens lets say evey 8 years in prepetuity (instead of every year). Thank you.

why should the formual change. Remeber it is for perpetuity. But if you wanted you could divide K by 8

I was thinking about it. We have to first convert the every 8 yr cashflow to a yearly cashflow which can then be used by using the perpetuity formula.
