What is data set that has five values and the mean is 34?

To have a dataset with five values and a mean of 34, the sum of all values must be ( 34 \times 5 = 170 ). An example of such a dataset could be ( 30, 32, 34, 36, 38 ), where the sum is indeed 170, and the mean is calculated as ( \frac{30 + 32 + 34 + 36 + 38}{5} = 34 ). Other combinations are also possible as long as they sum to 170.
