Question

triplul sumei a patru numere consecutive pare este 1044. afla numerele

Answer 1

Fie a,b,c,d cele 4 nr.
b=a+2
c=b+2=a+4
d=c+2=a+6

3*(a+b+c+d)=1044
3a+3b+3c+3d=1044
3a+3(a+2)+3(a+4)+3(a+6)=1044
3a+3a+6+3a+12+3a+18=1044
12a+36=1044
12a=1008
a=1008/12
a=84

b=a+2
b=84+2
b=86

c=a+4
c=84+4
c=88

d=a+6
d=84+6
d=90
