Răspuns :
daca numerele naturale consecutive sunt:
x ; x+1 ; x+2 atunci: x + x+1 + x+2 = 126
3x = 126 -3
x = 123:3=41
↓↓
Raspuns: 41 ; 42 ; 43 .
x ; x+1 ; x+2 atunci: x + x+1 + x+2 = 126
3x = 126 -3
x = 123:3=41

Raspuns: 41 ; 42 ; 43 .
a |-----|
b |-----|+1|
c |-----|+1|+1| } 126.
126 - 3 = 123 ( 3 segmente egale)
123 : 3 = 41 ( a)
41 +1 = 42 (b)
41 +1+1 = 43 (c)
Proba : 41 +42 +43 = 126.
b |-----|+1|
c |-----|+1|+1| } 126.
126 - 3 = 123 ( 3 segmente egale)
123 : 3 = 41 ( a)
41 +1 = 42 (b)
41 +1+1 = 43 (c)
Proba : 41 +42 +43 = 126.
