Numerele sunt a, a+1, a+2, a+3, a+4, a+5, a+6
a+a+1+a+2+a+3+a+4+a+5+a+6=35
7a+21=35
7a=14
a=2
Numerele sunt: 2, 3, 4, 5, 6, 7, 8
a+a+1+a+2+a+3+a+4+a+5+a+6=35

7a=14
a=2
Numerele sunt: 2, 3, 4, 5, 6, 7, 8
x+(x+1)+(x+2)+...+(x+6)=35
7x+21=35
7(x+3)=35
x+3=35/7 x+3=5
x=5-3 x=2
cele 7 nr sunt: 2,3,4,5,6,7,8.
