Question

suma a trei nr cosecutive este 102.afla nr.

Answer 1

a + a + 1 + a + 2 = 102
3a = 102 - 3
a = 99 : 3
a = 33
a + 1 = 33 + 1 = 34
a + 2 = 33 + 2 = 35

Answer 2

a+b+c=102
a,b,c=numere.consecutive
a,b,c=?
a=1segment
b=1segment+1
c=1segment+1+1
102-3=99(3segmente.egale)
99:3=33(a)
33+1=34(b)
33+1+1=35(c)
Verificare:33+34+35=102
