Mathematics - Binomial Theorem Question with Solution | TestHub

If $C_0,C_1,C_2,\dots \dots \dots ..C_n$ are the Binomial coefficients in the expansion $(1+x{)}^n$. ' n ' being even, then $C_0+\left(C_0+C_1\right)+\left(C_0+C_1+C_2\right)+\dots \dots \dots \left(C_0+C_1+C_2+\dots .+C_{n-1}\right)=$ is equal to
