Identify the numbers for which you want to find the mean: 210, 160, and 200.
Recall that the mean (or average) of a set of numbers is found by summing all the numbers and then dividing by the count of numbers.
Calculate the sum of the numbers: \(210 + 160 + 200\).
Count the total number of values, which in this case is 3.
Divide the sum by the number of values to find the mean: \(\frac{210 + 160 + 200}{3}\).
