# JEE maths #7

Algebra Level 4

Let $$C_0, C_1, C_2 ..., C_n$$ be the binomial coefficients of the expansion $$(1+x)^n$$, where $$n \in \mathbb N$$. If $$S_n = \dfrac {2C_0}2 + \dfrac {2^2C_1}6 + \dfrac {2^3C_2}{12} + \cdots + \dfrac {2^{n+1}C_n}{(n+1)(n+2)} + \dfrac 1{n+1} + \dfrac 1{2(n+1)(n+2)}$$, then find the value of $$\dfrac {S_7}{S_6}$$.
