How to Identify Arithmetic Patterns or Systems In Data Sets? Number pattern is a sequence or series of numbers where two consecutive numbers are linked through a mathematical relationship. In numbers and sequencing, the arithmetic patterns and systems are the simplest forms. It is a pattern that is formed using simple addition and subtraction. There is a common difference, "d" between two consecutive numbers in an arithmetic pattern. Identifying an arithmetic pattern within a data set can get tricky, but these simple tools can make it very simple and easy. Hundreds Chart - The hundreds chart comprises of 10 rows and 10 columns and counts from 1 to 100. The chart helps in finding out the common difference between two consecutive terms of a pattern. You can use the chart vertically, horizontally, and even diagonally to identify patterns. Addition Chart- The addition chart is another very helpful tool to identify arithmetic patterns in a data set. There are three principles of addition that we can clearly see in an addition chart are; - The sum of two even numbers is always even - The sum of two odd numbers is always even - The sum of an odd and an even number is always odd Number Line- The number line is the last and a very useful tool in identifying number patterns. It uses "terms" and not common differences to identify a pattern in a data set. Students learn how to find patterns in data through the help of these worksheets.
