Linear Extrapolation

In statistics, a process that consists of prolonging a statistical series by introducing a new term that obeys the rule of the series to the sequence of given terms.

Example

We represented the sequence of statistical data in the table below:

x	2	3	5	7	9
y	1	3	7	11	15

We determine that the relation that best describes this sequence is “y = 2x − 3.” By extrapolation, we can determine that, if x = 30, then y = 57.
