This project presents a new algorithm for identifying perfect numbers by leveraging beautiful triangular numbers. By discovering and implementing a unique pattern in the geometric structure of ...

We are told that a triangular number, when it is multiplied by 8 and then 1 is added to it, yields a square number. For example, we have that the third triangular number is 6, and 6 x 8 + = 49 = 7 x 7 ...

Ten is a triangular number, because 10 objects can be neatly arranged in an equilateral triangle. In general, a triangular number is a number that can be represented as a triangle with one object in ...

Figuring out Figurate Numbers The figure below shows the visual pattern for the first few triangular, square, pentagonal, and hexagonal numbers. These numbers are called figurate numbers. The number ...

Abstract: The aim of this paper is to explore a novel method for decision making based on triangular fuzzy number. In order to obtain the mathematical model of multi-attribute decision making (MADM) ...
