extrapolation

 [ek-strap″o-la´shun]
inference of one or more unknown values on the basis of that which is known or has been observed; usually applied to estimation beyond the upper and lower ranges of observed data as opposed to interpolation between data points.

extrapolation

/ex·trap·o·la·tion/ (ek-strap″ah-la´shun) inference of a value on the basis of that which is known or has been observed.

extrapolation

the estimation of a value beyond a given series, for example, the extension of the line of a graph beyond the calculated points.
