Math mini-contest problem for Day 4 on D.Buzz 😎

Ahmad played with numbers again. Starting with a positive number N, he added 3, then used the sum to divide N. The addition of 3 and using the sum to divide N is repeated indefinitely. What number will the result approach?

0! The more times you try this the closer you get to 0.

10/(10+3) = 0.77
10/(13+3) = 0.62
10/(16+3) = 0.53
....
10/(297+3) = 0.033
...
10/(30000000+3) => Almost 0~

Looks like you got the answer before me. I spent some time working out the math and had to double check lol.

0 is my answer. The number just keeps getting smaller if I work out the math.

I think it is 0.000......00001, where the no of zeros is infinite.

Answer for Day 4 Math Problem

0 🎯

Solution

Repeating the division of a positive number n by (n + 3) will give cumulative results closer and closer to zero. I don't know how to explain this further! 😅

Winner: @ahmadmangazap 🏅

1 HIVE has been sent to @ahmadmangazap's Hive account. 💰

  • If you look closely, @ahmadmangazap's answer is 0!, which can be read as "zero factorial", which is equal to 1. Next time, he should avoid answering a number with an exclamation mark beside it, to avoid being marked as wrong. 😆
  • @jfang003's correct answer was late by about a minute! ⏱️😆
  • If the process is repeated infinitely, the "final" result will be zero. It will not be 0.000...001, which is still not zero. 😐
  • I'm not sure where @minus-pi got his answer from. 😮🤔
  • @harpreetjanda's answer was correct, but his answer was submitted about 15 hours late from the first correct one. 😐

Like my request yesterday, please tell me if it is okay for you (the participant) to give remarks to your answers! 😅

it wasn't really clear to me if you meant (N+3)/N or N/(N+3) and calculated the first, because it nicely converges to the same value no matter which starting value you use.
