\n" ); document.write( "x = middle number
\n" ); document.write( "x = 39/3 = 13
\n" ); document.write( "(x-a)*x*(x+a) = 2184
\n" ); document.write( "(13-a)*13*(13+a) = 2184
\n" ); document.write( "(13-a)*(13+a) = 2184/13 = 168
\n" ); document.write( "169 - a^2 = 168
\n" ); document.write( "a = 1
\n" ); document.write( "--> 12, 13 & 14
