what is the use of a triangular number?

Best Answer...


Do you mean What are triangular numbers used for ?

Triangular numbers enumerate the items that can be arranged in a triangle. For example, ten bowling pins (10 is 4 triangles) and fifteen bowling pins (15 is 5 triangles).

Applications might include counting band members in a triangle formation, or napkins in a triangle pattern at a wedding.

Hope that helps :)
