A similar pattern is observed relating to squares, as opposed to triangles. To find the pattern, one must construct an analog to Pascal's triangle, whose entries are the coefficients of (x + 2) row number, instead of (x + 1) row number. There are a couple ways to do this. The simpler is to begin with row 0 = 1 and row 1 = 1, 2.
Scott Flansburg developed a mental math program called 'The Human Calculator. [9] ' Scott's course provides a step-by-step guide to becoming 'A Human Calculator.' Scott created this course to help people master mental mathematics. The training covers the unknown and hidden patterns behind numbers and how they work in our daily life.
The term can mean polygonal number; a number represented as a discrete r-dimensional regular geometric pattern of r-dimensional balls such as a polygonal number (for r = 2) or a polyhedral number (for r = 3). a member of the subset of the sets above containing only triangular numbers, pyramidal numbers, and their analogs in other dimensions.

A one-vertex crease pattern consists of a set of rays or creases drawn on a flat sheet of paper, all emanating from the same point interior to the sheet. (This point is called the vertex of the pattern.) Each crease must be folded, but the pattern does not specify whether the folds should be mountain folds or valley folds. The goal is to ...
A cutting-pattern, often called just pattern, is an arrangement of small rectangles on the stock sheet. It may be given as a sequence of points (x i,y i), for i in 1,...,m, where (x i,y i) is the bottom-left coordinate of rectangle i. In such a pattern, rectangle i occupies a horizontal segment (x i, x i +w i) and a vertical segment (y i, y i ...

The minimum pattern count problem: to find a minimum-pattern-count solution amongst the minimum-waste solutions. This is a very hard problem, even when the waste is known. [10] [11] [12] There is a conjecture that any equality-constrained one-dimensional instance with n sizes has at least one minimum waste solution with no more than n + 1 ...
