How do I find the arithmetic mean and the geometric mean?
arithmatic mean is all of the numbers added together divided by the amount of numbers its the average
Arithmetic mean of two numbers is just the average. (A+B)/2 Geometric mean is the number such that A:x is x:B \[\frac Ax = \frac xB\]Cross-multiply:\[AB=x^2\implies x=\sqrt{AB}\]
