David is borrowing \($150\),000 from Hartford Bank to open a road and off-road bicycle shop. Since David expects it to take a few years before the shop earns a sizeable profit, he has arranged for no payments on the loan until the end of the fourth year. The first and second payments are due 4 and 5 years, respectively, from today in the amounts of \($20\),000 each. Starting at the end of year 6, a series of 4 annual end-of-year payments will be made. The first of these is $X. 

Each subsequent payment is \($80\),000 greater than the previous payment. Draw the cash flow diagram from David’s perspective.
