Rectangular and triangular numbers
... Each counting number bigger than 0 is a rectangular number. The Greeks used the term rectangular number for the product of two consecutive numbers only, e.g. 42 = 6 x 7. When we draw rectangular numbers, they will look like this: ___ ...

Lecture 7: Sequences, Sums and Countability
... of finite size. Usually, mathematical sequences are infinite. To give an ordering to arbitrary elements, one has to start with a basic model of order. The basic model to start with is the set N = {0, 1, 2, 3, …} of natural numbers. For finite sets, the basic model of size n is: n = {1, 2, 3, 4, …, n ...
