Answer 1

pai faci si tu ei 2 numere de exemplu ; 2 si 6 si le aduni apoi imparti la 2 deoarece sunt doua numere si media aritmetica ati va da 4  si tot asa cu orce fel de numere nu este greu .Soer ca te-am ajutat 

Answer 2

   
[tex] \frac{8+6}{2}=7;~~~ \frac{7+3}{2}=5;~~~ \frac{20+60}{2}=40;~~~ \frac{11+17}{2}=14;~~~ \frac{15+25}{2}=20; \\ \\ \frac{9+7}{2}=8;~~~ \frac{8+4}{2}=6;~~~ \frac{21+61}{2}=41;~~~ \frac{12+18}{2}=15;~~~ \frac{16+26}{2}=21; \\ \\ \frac{10+8}{2}=9;~~~ \frac{9+5}{2}=7;~~~ \frac{22+62}{2}=42;~~~ \frac{13+19}{2}=16;~~~ \frac{17+27}{2}=22; \\ \\ \frac{7+5}{2}=6;~~~ \frac{6+2}{2}=4;~~~ \frac{19+59}{2}=39;~~~ \frac{10+16}{2}=13;~~~ \frac{14+24}{2}=19; [/tex]

[tex] \frac{6+4}{2}=5;~~~ \frac{5+1}{2}=3;~~~ \frac{18+58}{2}=38;~~~ \frac{9+15}{2}=12;~~~ \frac{13+23}{2}=18; \\ \\ \frac{12+8}{2}=10;~~~ \frac{10+12}{2}=11;~~~ \frac{36+118}{2}=77;~~~ \frac{18+30}{2}=24;~~~ \frac{26+46}{2}=36; \\ \\ [/tex]

In total 30 de medii.
