en.wikipedia.org/wiki/Extrapolation

In mathematics, extrapolation is a type of estimation, beyond the original observation range, the value of a variable on the basis of its relationship with another variable.It is similar to interpolation, which produces estimates between known observations, but extrapolation is subject to greater uncertainty and a higher risk of producing meaningless results.

Learning about Extrapolation What Is Extrapolation? Extrapolation in math is the process of finding a value beyond a set of given values. You most often have to use extrapolation when you have to find values in a sequence, or when making graphs.

extrapolation and interpolation: Extrapolation is an estimation of a value based on extending a known sequence of values or facts beyond the area that is certainly known. In a general sense, to extrapolate is to infer something that is not explicitly stated from existing information .

In Statistics, Extrapolation is a process of estimating the value beyond the distinct range of the given variable. The meaning of this term is the process of estimating something if the present situation continues. It is an important concept not only in Mathematics but also in other disciplines like Psychology, Sociology, Statistics etc with some categorical data.

Extrapolation and interpolation are both used to estimate hypothetical values for a variable based on other observations. There are a variety of interpolation and extrapolation methods based on the overall trend that is observed in the data.These two methods have names that are very similar.

Extrapolation also becomes more and more inaccurate the further you extrapolate. If you’re extending a line on a graph only a little bit, chances are that you’ll get it somewhat right. You can’t really extend the graph a long way without more information about the data and trends however.
