## What is the problem with extrapolating to far into the future?

So what is wrong with extrapolation. First, it is not easy to model the past. Second, it is hard to know whether a model from the past can be used for the future. Behind both assertions dwell deep questions about causality or ergodicity, sufficiency of explanatory variables, etc.

extrapolation “less reliable” than interpolation that is true not in all contexts. It may be true when a specific number, more than one, of known points is demanded to infer the unknown point.

## What do you mean by trend extrapolation discuss its advantages and limitations?

Trend extrapolation is one aspect of the larger field of trend (or trendline) analysis. It attempts to extend known data points to regions beyond the timeframe of known datapoints, almost always in an attempt to predict future values with some degree of probability. However, the assumptions made are critical.
