first solve for x
given
x - 1, 12, x, x + 1, and 13 and they sum to 58
(x-1) + 12+x+(x+1)+13=58
3x+25=58
x=11
----
Now, replace x=11 to find the actual five numbers
10,12,11,12,13
-----
order the numbers
10,11,12,12,13
---
the median is the value such that half the numbers are below and half above it
if the set of numbers is odd, the median is the middle value, if the set of numbers is even, the median is the average of the two middle values
--
so median is the 3rd value: 12
