given expression is (2+x)^2n
now we know that the number of terms in its expansion would be 2n+1.
so, (n+1)th term would be middle term, which is 2nCn*2^n*x^(2n-n)
or 2nCn*2^n*x^n.
so, coeff of x^n is 
2nCn*2^n
kindly approve :=)

Dear student
 
here are 2n +1 terms hence n+1 th term is middle.
Hence T2n+1 = 2nCn xn
 
hence coefficient = 2nCn
