Let’s back trace from the end to the start.
Logic: they gave the same number of tractor to the other person as that person had already with him. That means at the end of every step the number of tractors with people other than the current lender is doubled. And the number of tractor others had is the decrement in his number of tractors. So for a back trace half the number of tractors with the people other then the lender and add the decreased amount to the lender as follows
A---------------B---------------C
24--------------24--------------24
12--------------12--------------24+12+12=48
6---------------12+6+24=42------24
6+21+12=39------21--------------12
