Question 1196099
-------------------------
abcde = number
a=b+2
b=c+2
d=2d/2
e=2d/4
-------------------------


Notice how the given facts also mean that d=d, which is redundant, and that {{{e=d/2}}}.   This is the same as  {{{d=2e}}}; and therefore some possible choices of d should be exactly one of  2, 4, 6, 8.  


a must not be 0. If it were, then cannot have the five-digit number.
a may be exactly one of  1, 2, 3, 4, 5, 6, 7.


This not a finished solution; only some thoughts on the way to a solution.
