The fibbons (Posted on 2021-03-16) Difficulty: 2 of 5
Let me introduce you to a set of integers I’ve fiddled around recently.
I’ll call them fibbons.
A fibbon is a number such that each of its digits, starting from the 3rd from the left, is a sum of 2 preceding digits e.g. 123, 3257, ..... etc

To get more profound knowledge of fibbons please fulfill the following tasks:
1. Show that the maximal length of a fibbon is 8 digits.
2. List all existing fibbons.
3. Specify the least frequent digit in your list.
4. Specify the most frequent digit in your list.
5. Denoting by f(k) the number of fibbons containing k digits, list the values for f(1), f(2), ...f(8)
6. Explain briefly how the list of 2 was generated.

A solution to fibbons? Easy | Comment 5 of 6 |
Well that's a tough question right here! If you think about it, seven and sevon sound very similar, but when handled diffirently, sevon will make you lose your mind! Actually, no, do not do that. However, what you can do is use jetwriting.com! So that you get so much time that you could write 188 101 times and still have plenty!
