\n" ); document.write( "\n" ); document.write( "the ratio by which the terms increase is \"1%2F4\" (if you multiply first term by \"1%2F4\" you get second term \"1%2F4\",if you multiply second term by \"1%2F4\" you get \"%281%2F4%29%281%2F4%29=1%2F16\", etc.) \r

\n" ); document.write( "\"\"Sn\"\" is the sum of the geometric series, \"\"a%5B1%5D\"\" is the first term in the series, \"\"n\"\" is the number of terms and \"\"r\"\" is the ratio by which the terms increase
