Linear Extrapolation

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.


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.
