The 3rd octagonal number is 21. An octagonal number represents a series of dots arranged in the shape of an octagon, with each successive layer adding more dots to form the shape. The formula for the nth octagonal number is Oₙ = 3n² - 2n. In this case, the 3rd octagonal number equals 21, which is the sum of the first 3rd terms in the octagonal sequence. These numbers are widely used in geometry and number theory to explore octagonal shapes and their growth.
Understanding the previous and next Octagonal Number helps in identifying numerical relationships and patterns. We explore both the preceding and succeeding values based on different property types. The 2nd Octagonal Number is 8. This is the Octagonal Number that comes before the 3rd Octagonal Number. The 4th Octagonal Number is 40. This is the Octagonal Number that comes after the 3rd Octagonal Number. By understanding the previous and next values, we can recognize numerical progressions and sequences, making calculations and analysis easier.
