The 2nd octadecagonal number is 18. This means 18 dots can be arranged to form an 18-sided polygon (octadecagon) with 2 layers. The formula used to calculate the nth octadecagonal number is Oₙ = 8n² - 7n. This result reveals the growth of the pattern as each layer is added. Octadecagonal numbers play an important role in mathematics, especially in geometry and number theory, where they describe patterns and help to analyze polygonal shapes.
Understanding the previous and next Octadecagonal Number helps in identifying numerical relationships and patterns. We explore both the preceding and succeeding values based on different property types. The 1st Octadecagonal Number is 1. This is the Octadecagonal Number that comes before the 2nd Octadecagonal Number. The 3rd Octadecagonal Number is 51. This is the Octadecagonal Number that comes after the 2nd Octadecagonal Number. By understanding the previous and next values, we can recognize numerical progressions and sequences, making calculations and analysis easier.
