Question 859247
x = first number


x+1 = next consecutive number after 'x'


x+2 = next consecutive number after 'x+1'




They add to 27, so,



{{{x+(x+1)+(x+2) = 27}}}



{{{x+x+1+x+2 = 27}}}



{{{3x+3 = 27}}}



{{{3x = 27-3}}}



{{{3x = 24}}}



{{{x = 24/3}}}



{{{x = 8}}}



{{{x+1=8+1=9}}}



{{{x+2=8+2=10}}}



So,



{{{x=8}}}



{{{x+1=9}}}



{{{x+2=10}}}



The three numbers are: <font size=4 color="red">8,9,10</font>



Quick Check: 8+9+10 = 27, so that works out.
