E, the age for Evan.
Joel is some E+d;
and Alex is some E+2d.

E%2BE%2Bd%2BE%2B2d=39
3E%2B3d=39
E%2Bd=13----------------this would be Joel's age. Joel is the in-between age of Evan and Alex.

The equal age differences mean that Joel's age is the average of the three ages.

39/3 = 13

Joel is 13 years old.
