Fie a,b,c cele trei numere.
/--------------/ a
/-------------/---/---/ b
/-------------/----/---/---/---/ c
___________________________________ suma 255.
255-6=249 ( egalarea partilor )
249:3=83 ( primul numar )
83+2=85 ( al doilea numar )
85+2=87 ( al treilea numar )
a + b + c = 83 + 85 + 87 = 255 ( A )
