What is the difference between arithmetic and geometrical series i'm not sure if this is what you mean by how do they look like geometric and arithmetic . Arithmetic mean should have been called additive mean, while a better name for geometric mean would be multiplicative mean harmonic mean would be inverse mean, and the world would be good while we can't change names, we can try to steer clear of the pitfalls associated with using arithmetic mean all the time. The most obvious difference between the arithmetic mean and the geometric mean for a data set is how they are calculated the arithmetic mean is calculated by adding up all the numbers in a data set and dividing the result by the total number of data points. In mathematics, the inequality of arithmetic and geometric means, or more briefly the am–gm inequality, states that the arithmetic mean of a list of non-negative real numbers is greater than or equal to the geometric mean of the same list and further, that the two means are equal if and only if every number in the list is the same.
