Hello candidate,

The total number of terms in the expression of (1+x)^2n+1 is equal to 2n+2. So, the middle term of the expression is 2n+2/2= (n+1)th term.

So, the term is 2n+1Cn+1* x^n+1*1^n+1, where the term C represents Combination of Permutation and Combination.

Hope that this Information helps you!!

Hope it helps.
