\n" ); document.write( "1/2, 2, 27/8, 4, ...

\n" ); document.write( "Given that the 1st and 3rd terms are fractions but the others are not, rewrite the sequence as all fractions, using denominators that form a recognizable pattern.

\n" ); document.write( "The denominator of the 1st term is 2; the denominator of the 3rd term is 8. So one \"nice\" pattern for the denominators would be 2, 4, 8, 16, .... Using those denominators, the sequence is

\n" ); document.write( "1/2, 8/4, 27/8, 64/16, ...

\n" ); document.write( "The numerators are now 1, 8, 27, 64, ..., which are 1^3, 2^3, 3^3, and 4^3. So the pattern for the sequence appears to be

\n" ); document.write( "\"t%28n%29+=+n%5E3%2F2%5En\"
