Hire purchase in ffm

hello, i have some problem for understanding this question and answer in my textbook , i hope you can explain this to me

For example, if a company buys a car costing $10,000 under an HP(hire purchase) agreement, the car supplier might provide HP finance over a three year period at an interest cost of 10%, and the HP payments might be say, as follows

capital element($) interest element($) total HP payment($)
Year 0 : down payment 2540 0 2540
year 1 2254 746 3000
year 2 2479 521 3000
year 3 2727 273 3000
total 10000 1540 11540

so the part that i dont understand is where does capital element year 1,2,3 come from? does total HP for year 1,2,3 need to be 3000?
