Question

suma a 4 numere pare consecutive este 164. aflati numerele

Answer 1

k+k+2+k+4+K+6= 164
=> 4K+ 2+4+6=164
4K + 12= 164 / -12
=> 4K = 152=> K= 152:4=> k=38 (primul numar)
K2= 38+2=> K2= 40
K3= 38+4=>K3= 42
K4=38+6=> K4=44
Suma numerelor: 38+40+42+44=164 :)

Answer 2

numim cel mai mic numar   x ; x+(x+2)+(x+4)+(x+6)=164 ; 4x=164-(2
+4+6)  
4x=164-12=152 
x=152:4 
x=38 
x+2=38+2=40 
x+4=38+4=42 
x+6=38+6=44
