Extrapolate

If you extrapolate something, you are inferring or finding out an unknown using the known. Now, this can occur in math, science, and mysteries. Math? In algebra, using the known information to find out the unknown information. Science? In science, there are many formulas so there must be a way to use extrapolation. Mysteries? Well, you use extrapolation and use whatever you know already and match it up with what has happened. So, as far as I know, three subjects can use extrapolation. Bye!
