A Pentagonal number represents a pentagon, a five-sided polygon. It can be calculated using the formula: Pₙ = (3n² - n) / 2, where n is the position in the sequence. Pentagonal numbers form a pattern that visually arranges into a pentagonal shape, with each number adding another layer to the structure. For example, the 4th pentagonal number is 22, which represents the sum of the first 4 terms in the pentagonal sequence. These numbers can be arranged geometrically in a pentagonal shape with 4 layers of dots.
Understanding the previous and next Pentagonal Number helps in identifying numerical relationships and patterns. We explore both the preceding and succeeding values based on different property types. The 3rd Pentagonal Number is 12. This is the Pentagonal Number that comes before the 4th Pentagonal Number. The 5th Pentagonal Number is 35. This is the Pentagonal Number that comes after the 4th Pentagonal Number. By understanding the previous and next values, we can recognize numerical progressions and sequences, making calculations and analysis easier.
