plasa neagra |__|
I plasa alba |__|
II plasa alba |__|..+1..|
III plasa alba |__|..+1..|..+1..|
IV plasa alba |__|..+1..|..+1..|..+1..|
V plasa alba |__|..+1..|..+1..|..+1..|..+1..|
VI plasa alba |__|..+1..|..+1..|..+1..|..+1..|..+1..|
VII plasa alba |__|..+1..|..+1..|..+1..|..+1..|..+1..|..+1..|

Total mingi =189

189 -(1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1)
=189-21
=168

1+1+1+1+1+1+1+1=8 (segmente egale)

168 : 8 = 21 (valoarea unui segment)

plasa neagra=1×21=21 (mingi)
I plasa alba=1×2+=21 (mingi)
II plasa alba=1×21+1=21+1=22 (mingi)
III plasa alba=1×21+2×1=21+2=23 (mingi
IV plasa alba=1×21+3×1=21+3=24 (mingi)
V plasa alba=1×21+4×1=21+4=25 (mingi)
VI plasa alba=1×21+5×1=21+5=26 (mingi)
VII plasa alba=1×21+6×1=21+6=27 (mingi)
