Question

Suma a trei nr consecutive este 51.Aflati nr !*:))

Answer 1

numere consecutive au diferenta 1
a+b+c=51
b=a+1
c=b+1=a+2
a+a+1+a+2=51
3a+3=51
3a=51-3
3a=48
a=48/3
a=16
b=16+1=17
c=17+1=18

Answer 2

a + b + c = 51
a = a
b = a + 1
c = a + 2
a + a+1 + a +2 = 51
3a = 51 - 1 -2
3a = 48
a = 48 : 3
a = 16
b = 16 + 1= 17
c = a +2 = 16 + 2 = 18
verificam
16 + 17 + 18 = 51
