I had Python test on friday and one task was related to pentabonacci numbers. I still have not figured it out because I never trained such tasks. You can find some information here and on GeeksForGeeks (by the way, it is really good explanation!).
But I now understand that without knowing this background it would have not been possible to solve this task despite it being 1 min task in Excel 🙂
Need to know: N-bonacci numbers with first N-1 initial terms set to 0 and Nth initial term set to 1. And everything that comes after is the sum of N previous numbers.
