Question

Media aritmetica a cinci numere naturale consecutive este 3. Determinati numerele!
Va rog frumos!!!!

Answer 1

[a+(a+1)+(a+2)+(a+3)+(a+4)]:5=3
a+(a+1)+(a+2)+(a+3)+(a+4)=5×3=15
a+(a+1)+(a+2)+(a+3)+(a+4)=15
5a+10=15
5a=15-10
5a=5
a=5:5
a=1
a+1=1+1=2
a+2=1+2=3
a+3=1+3=4
a+4=1+4=5
Numerele sunt: 1,2,3,4,5
V: (1+2+3+4+5):5=15:5=3
