Mean is sum divided by 15. It is 90/15=6
Median is middle number which is 8th from bottom if numbers are ordered. It is 5
Mode is the most common number. It is 5.
Mode is generally the least useful, except as a descriptor.
The fact that the mean is greater than the median means that the distribution has a right skew, and that a larger number is affecting it. Those numbers are 12 and 15.
The central portion of this distribution is 5 (median) and 6 (mean).
