In a set of evenly spaced integers, the mean = median.
For example take:
5, 10, 15
What is the median?...10
And the mean?...10
In this question, we have 7 consecutive integers and the smallest one is x.
Thus, the integers are:
x, (x+1), (x+2), (x+3), (x+4), (x+5), (x+6)
The middle number (x+3) is both the median and mean of the set.
