Conjecture about an unknown by projecting information about something known; predict by projecting past experience. In math and science, to extrapolate is to infer values in an unobserved
interval from values in an observed interval. For instance, from the points (1,4) and (3, 8), you could extrapolate the point (5, 12), since it would be on the same line.
No, I've never been to Bryn Mawr, but I've visited several small, private womens colleges in the Northeast, so I think I can extrapolate.
