Triangle, pentagonal, and hexagonal numbers are generated by the following formulae: Triangle: T n = n ( n + 1) 2 1, 3, 6, 10, 15, …. Pentagonal: P n = n ( 3 n − 1) 2 1, 5, 12, 22, 35, …. Hexagonal: H n = n ( 2 n − 1) 1, 6, 15, 28, 45, …. It can be verified that T 285 = P ... WebThese numbers are called figurate numbers. The number of dots in an individual polygonal shape represents a particular figurate number for each pattern. For example, the first five triangular numbers are 1, 3, 6, 10, 15. The first four square numbers are 1, 4, 9, 16, and the first three pentagonal numbers are 1, 5, 12. The nth square number is n 2.
