Pattern
A pattern is an idea, a concept or a model. The model is usually abstract, and can then be applied to the domain where it is used. Pattern matching is checking if a certain pattern is present. Many patterns can directly be recognised by the senses.
Some patterns are based on the fact that there are repetitions, that a certain thing occurs over and over again. An example of a simple pattern might be the tiling of a floor, in a bathroom. For example, lots of bathrooms have a paisley or floral tiling pattern, which, I think, is great.
In Computer science, Design patterns are model solutions for problems that occur very often.
Mathematical patterns
In Mathematics, there are many different patterns. For example, the Fibonacci sequence is a complex type of pattern. There are some simple ones like:
1, 2, 4, 8, 16, ...
In this pattern, the next number is the product of the previous number multiplied by 2.
