Let number of rungs be R
\n" );
document.write( "Then middle, or median rung = 
\n" );
document.write( "Moving up and down the ladder, we get:  
\n" );
document.write( "
\n" );
document.write( "R + 1 + 14 = 2R -------- Multiplying by LCD, 2
\n" );
document.write( "R + 15 = 2R
\n" );
document.write( "R – 2R = - 15
\n" );
document.write( "- R = - 15
\n" );
document.write( "R, or number of rungs = , or  \n" );
document.write( "

\n" );
