The ratio is 7/8
\n" ); document.write( "sum is Sn=a/(1-r)
\n" ); document.write( "=16/(1/8)
\n" ); document.write( "=128\r
\n" ); document.write( "\n" ); document.write( "check with a high power of r such as r^100
\n" ); document.write( "a(r^20-1))/(r-1)
\n" ); document.write( "=127.9997
\n" ); document.write( "
