Answer 2

Explanation:

Some important properties of the arithmetic mean are as follows: The sum of deviations of the items from their arithmetic mean is always zero, i.e. ∑(x – X) = 0. ... If each item in the arithmetic series is substituted by the mean, then the sum of these replacements will be equal to the sum of the specific items.
