Triangular numbers have no other name except "triangle numbers."

They represent numbers of objects that can be arranged as equilateral triangles with side n.

The number of objects required is defined by the formula T = n (n+1)/2 where successive rows will have from 1 to n objects.

The first 6 triangle numbers are 1, 3, 6, 10, 15, and 21.
