Use recursive functions to do the following:

At the beginning of the year, Michael Jacob added 20000 yuan to the oil card. it is known that Michael Jacob will refuel 4 times a month at a cost of 350*4 yuan. Every 10 times a three-person refueling service is used, the petrol station will enjoy an off price and a off price. Q: How many times should I recharge the card after I refuel it? What is the balance of the oil card after each refueling? Wang's parents...

2. 1. Mr. Wang's parents saved him 20000 yuan of living expenses at school. it is known that Mr. Wang will pay 1500 yuan every month after the bank's interest rate. Assume that the current monthly interest rate is 0.32%.
      So what is the balance after Mr. Smith receives the money? How many times have Mr. Wang finished?

1. Recursively output the following numbers

5, 3, 1, 3, 5
