a geometric sequence has a sixth term of 24 and a common ratio of 2/3. find the first three terms\r
\n" ); document.write( "\n" ); document.write( "

\n" ); document.write( "GP formula: \"a%5Bn%5D+=+a%5B1%5Dr%5E%28n+-+1%29\"
\n" ); document.write( "\"a%5B6%5D+=+a%5B1%5D%282%2F3%29%5E%286+-+1%29\"___Substituting 6 for n, and \"2%2F3\" for r
\n" ); document.write( "\"24+=+a%5B1%5D%282%2F3%29%5E5\"_____Substituting 24 for \"a%5Bn%5D\"
\n" ); document.write( "\"24+=+a%5B1%5D%2832%2F243%29\"
\n" ); document.write( "\"a%5B1%5D+=+24\"÷\"32%2F243\"
\n" ); document.write( "\"a%5B1%5D+=+24%28243%2F32%29\"
\n" ); document.write( "\"a%5B1%5D+=+3cross%2824%29%28243%2F4cross%2832%29%29\"
\n" ); document.write( "\"a%5B1%5D+=+729%2F4%29\", or \"highlight_green%28a%5B1%5D+=+182.25%29\"\r
\n" ); document.write( "\n" ); document.write( "The first term, or \"a%5B1%5D\"(182.25), and the common ratio, or r (\"2%2F3\"), should be substituted into the GP formula,
\n" ); document.write( "\"a%5Bn%5D+=+a%5B1%5Dr%5E%28n+-+1%29\" to determine the 2nd term (\"a%5B2%5D\"), and 3rd term (\"a%5B3%5D\").\r
\n" ); document.write( "\n" ); document.write( "You'll then have all 3 terms.\r
\n" ); document.write( "\n" ); document.write( "You can do the check!! \r
