is that the arithmetic mean tends to overstate the actual average return by a greater and greater amount the more the inputs vary. In Example 2, the returns increased by 10% in year one, 150% in year two and then decreased by 30% in year 3. This is an increase of 130% from the ...

However, it is worth pointing out that the proof that a series is convergent does not necessarily mean that we can obtain its sum easily. In fact, the calculations of such summation can be tricky, and even impossible in many cases. There are many other convergence tests, including the term...
In statistics, the geometric mean defines a specifically calculated average value of the set of "N" numbers. The geometric mean is the "N"-th root of the product (N1 x N2 x ...Nn) of "N" numbers in the set. For example, if the set comprises two numbers,
