Essentially, if want to list some values with a given mean, you can assume that they all have this value, so a correct answer will be:
26,26,26,26,26,26,26,26,
You can also vary the values, as long as their sum remains the same (the sum and the number of values decide the mean).
For example, you can add one and remove one:
27,25,26,26,26,26,26,26,
