A ratio of the $5^{th}$ term from the beginning to the $5^{th}$ term from the end in the binomial expansion of $\left( {{2^{1/3}} + \frac{1}{{2{{\left( 3 \right)}^{1/3}}}}} \right)^{10}$ is
$1:2{\left( 6 \right)^{\frac{1}{3}}}$
$1:4{\left( 16 \right)^{\frac{1}{3}}}$
$4{\left( {36} \right)^{\frac{1}{3}}}\,:\,1$
$2{\left( {36} \right)^{\frac{1}{3}}}\,:\,1$
