hi sriraman
take 2^2 common from numerator we get (1^2+2^2+3^2+....(n)^2
use the standard formula
in numerator add and subtract
2^2+4^2+6^2+....(2n)^2
again with some algebraic steps u will get expression for which you can use formula
and then u will get the inequality in n
2^2+4^2+6^2+....(2n)^2 /1^2+3^2+5^2+...(2n-1)^2 > 1.01
