A Decagonal number is a figurate number that represents a decagon, a ten-sided polygon. The nth decagonal number is determined by the formula Dₙ = 4n² - 3n. It can be arranged visually as a decagon, where each successive number adds a new layer to the shape. For example, the 2nd decagonal number is 10. This means the 2nd decagonal number can be represented as a decagon with 2 distinct layers. Decagonal numbers are widely used in number theory, geometry, and combinatorics, representing patterns and shapes relevant to ten-sided polygons.
Understanding the previous and next Decagonal Number helps in identifying numerical relationships and patterns. We explore both the preceding and succeeding values based on different property types. The 1st Decagonal Number is 1. This is the Decagonal Number that comes before the 2nd Decagonal Number. The 3rd Decagonal Number is 27. This is the Decagonal Number that comes after the 2nd Decagonal Number. By understanding the previous and next values, we can recognize numerical progressions and sequences, making calculations and analysis easier.
