Look at the numbers in terms of what powers they are of what numbers
\n" ); document.write( "\"2%5E2+=+4\"
\n" ); document.write( "\"2%5E3+=+8\"
\n" ); document.write( "\"2%5E4+=+16\" etc.
\n" ); document.write( "and
\n" ); document.write( "\"3%5E2+=+9\"
\n" ); document.write( "\"3%5E3+=+27\"
\n" ); document.write( "\"3%5E4+=+81\" etc.
\n" ); document.write( "look at your sequence number by number
\n" ); document.write( "1,8,27,64,125
\n" ); document.write( "\"1+=+1%5E2\"
\n" ); document.write( "\"8+=+2%5E3\"
\n" ); document.write( "\"27+=+3%5E3\"
\n" ); document.write( "\"64+=+4%5E3\"
\n" ); document.write( "\"125+=+5%5E3\"
\n" ); document.write( "The first one is out of place but \"1%5E2+=+1\" and \"1%5E3+=+1\" also
\n" ); document.write( "so, the sequence is \"n%5E3\" where n is the position in the sequence.
\n" ); document.write( "Test yourself. What is the 11th term?
\n" ); document.write( "\"1331+=+11%5E3\"
\n" ); document.write( "what is the 10,000th term?
\n" ); document.write( "\"10%5E12+=+10000%5E3\"
\n" ); document.write( "------------------
\n" ); document.write( " a, a+d, a+2d, a+3d, a+4d,...
\n" ); document.write( "a is the same in each term so, it's a + something
\n" ); document.write( "The multiplier for d looks like its position in the series minus one
\n" ); document.write( "n = position
\n" ); document.write( "\"a+%2B+%28n-1%29d\" answer
\n" ); document.write( "test this to see if it works for each term
\n" ); document.write( "1st term: \"a+%2B+%281-1%29d+=+a\"
\n" ); document.write( "2nd term: \"a+%2B+%282-1%29d+=+a+%2B+d\" etc.
\n" ); document.write( "
\n" ); document.write( "
\n" );
