Table comparing Fibonacci Tribonacci and Tetranacci sequences and their limiting ratios

Folge	Regel	Terme	Grenzwert
Fibonacci	Summe von 2	1,1,2,3,5,8,13,21...	φ≈1,618
Tribonacci	Summe von 3	1,1,2,4,7,13,24...	T≈1,839
Tetranacci	Summe von 4	1,1,2,4,8,15,29...	≈1,928
Pentanacci	Summe von 5	1,1,2,4,8,16,31...	≈1,966
n-nacci	Summe von n	...	→ 2
Je mehr Terme summiert werden, desto näher rückt die Wachstumsrate an 2.
