Extended or estimated data, patterns, or trends beyond known values by assuming the pattern continues in the same way.
From Latin 'extra' (beyond) + 'polatus' (estimated). Coined in the 1800s as a mathematical term, combining Latin roots to describe extending graphs or data lines beyond observed points.
