Periodicity is demonstrated by the repeating patterns or trends that occur at regular intervals in a specific set of data or elements. This can be seen in the periodic table of elements, where elements are arranged in order of increasing atomic number and show similar chemical properties at regular intervals. In mathematics, periodicity is shown in functions that repeat their values at regular intervals, such as sine and cosine functions. Overall, periodicity is a fundamental concept that helps us understand and predict patterns in various disciplines. **

Periodicity can be shown by identifying a repeating pattern or trend in a set of data or a physical phenomenon. This can be done by graphing the data and looking for regular peaks and troughs, or by analyzing the data for consistent intervals or cycles. In the case of physical phenomena, periodicity can be demonstrated by observing the regular occurrence of a certain behavior or event at predictable intervals. Additionally, mathematical tools such as Fourier analysis can be used to identify and quantify periodic patterns in data. **

The periodicity of a sequence refers to the length of the shortest repeating pattern within the sequence. In other words, it is the number of terms in the sequence before it starts to repeat itself. For example, in a sequence like 1, 2, 3, 1, 2, 3, the periodicity is 3 because the pattern 1, 2, 3 repeats every 3 terms. Understanding the periodicity of a sequence can help in identifying patterns and predicting future terms in the sequence. **
