Bonjour,

3 entiers consécutifs:

n+n+1+n+2

n+n+1+n+2 = 231

3n+3 = 231

3n = 231-3

3n =228

n= 228/3

n=76

=> 76; 77; 78

n+n+1+n+2 = 229

3n+3 = 229

3n = 229-3

3n = 226

n = 226/3

n= 75,3333

impossible

n+n+1+n+2  = 3 093

3n+3 = 3 093

3n= 3 093-3

3n =3 090

n = 3 090/3

n=1 030

=> 1 030;  1 031; 1 032
