suma a 5 numere impare consecutive , care au suma 155

Answer 1

fie a, a+2, a+4, a+6, a+8 numerele impare 
=> 5a + 20 = 155 => 5a = 155- 20 => 5a = 125
=> a = 25 
=> numerele sunt: 25, 27, 29, 31, 33

Answer 2

(__)
(__)+2
(__)+4
(__)+6
(__)+8

Suma lor este 155
5 segmente egale +2+4+6+8=155
5 segmente egale +20=155
5 segmente egale=155-20
5 segmente egale=135
1 segment (primul numar)=135:5=27
urmatoarele numere sunt 29,31,33,35

27+29+31+33+35=155
