Răspuns :

a+a+1+a+2+a+3+a+4=230
5a+10=230
5a=230-10
5a=220
a=44
b=45
c=46
d=47
e=48
a+b+c+d+e=230

a |-----|
b |-----|---|
c |-----|---|---|
d |-----|---|---|---| 230
e |-----|---|---|---|---|

5 p +10 = 230
5 p = 230 - 10
5 p = 220
p = 220:5
p = 44

a = 44
b = 44 + 1 = 45
c = 44 + 1 + 1 = 46
d = 44 + 1 + 1 + 1 = 47
e = 44 + 1 + 1 + 1 + 1 = 48

VERIFICARE : 44+45+46+47+48 = 89 +46 + 47 + 48 = 135 + 47 + 48 = 182 + 48 = 230
