You can put this solution on YOUR website!
Look for instruction on Geometric Series.\r

\n" ); document.write( "\n" ); document.write( "150+150/2+150/4+150/8+150/16+....
\n" ); document.write( "\"r+=+1%2F2\".
\n" ); document.write( "\"a%5B1%5D=150\".\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"r%3C1\" means the series converges and you can use the formula, \"Sum=a%5B1%5D%2F%281-r%29\".
