Answer:In mathematics, an arithmetic mean, often simply called the "mean," is a measure of central tendency. It is calculated by adding up a set of numbers and then dividing the sum by the count of those numbers.For example, to find the arithmetic mean of the numbers 2, 4, and 6:Add the numbers together: 2+4+6=122+4+6=12.Divide the sum by the number of values (which is 3 in this case): 123=4312 =4.So, the arithmetic mean of 2, 4, and 6 is 4.
