Răspuns :
a+b+c-987
a+a+1+a+2=987⇒3a=987-3⇒3a=984⇒ a=984:3=328
a=328
b=a+1⇒b=329
c=a+2⇒c=328+2=330⇒c=330
a+a+1+a+2=987⇒3a=987-3⇒3a=984⇒ a=984:3=328
a=328
b=a+1⇒b=329
c=a+2⇒c=328+2=330⇒c=330
Numerele consecutive sunt de forma :
x,x+1,x+2
Suma lor este:
x+x+1+x+2=987
3x+3=987
3x=984
De unde obtinem x=328
x+1=329
x+2=330
x,x+1,x+2
Suma lor este:
x+x+1+x+2=987
3x+3=987
3x=984
De unde obtinem x=328
x+1=329
x+2=330
