You can put this solution on YOUR website!
Lets suppose X is the 3rd number.\r
\n" ); document.write( "\n" ); document.write( "so average V = (X+Y+Z)/3\r
\n" ); document.write( "\n" ); document.write( " 3V = X + Y + Z
\n" ); document.write( " X = 3V - Y - Z
\n" ); document.write( "So the answer is D. 3V - Z - Y
\n" ); document.write( "
\n" );
