Dreieckszahlen

Einleitung

Eine Dreieckszahl ist eine Zahl welche sich aus der Summe von 1 und aller darauffolgenden natürlichen Zahlen (ganze Zahlen) bis zu einer Obergrenze “n” ergibt.
zum Beispiel: d4 = 1 + 2 + 3 + 4 = 10 (ist die 4-te Dreieckszahl)
Man zählt sie zusammen mit den Quadratzahlen , Fünfeckszahlen und Sechseckszahlen zur Klasse der Polygonalzahlen.
Wie alle regulären figurierten Zahlen lassen sich auch die Dreieckszahlen im Pascalschen Dreieck ablesen.

Dreieckszahl von 0


Hier finden Sie die Dreieckszahl von 0.
Bei einigen Autoren ist die Null keine Dreieckszahl, sodass die Zahlenfolge erst mit der Eins beginnt.

Δ0 = 0
