WebIn addition to combining pairs of terms of the original sum N choose i to get a sum of terms of the form N+1 choose 2j+c, where c is always 0 or always 1, one can now take the top … WebThe correct option is C. 2nCn−2. We can re-write the terms as nC0nCn−2+nC1nCn−3+nC2nCn−4.....nCn−2nC0. We wrote it this way because, we can see that the p numbers in the subscript add up to n - 2 (e.g. In nC0nCn−2, the subscripts are n - 2 and 0) ⇒ Lets consider the expansion of (1+x)n(x+n)n and find the coefficient of xn−2.
