The equation is not true for any value of n. If the equation is supposed to have a solution, then you have not shown the equation correctly.

(n-1)C(n-3) is the same as (n-1)C(2); (n+1)C(n-2) is the same as (n+1)C(3). The equation is then

4%28%28n-1%29%28n-2%29%2F2%29+=+3%28%28n%2B1%29%28n%29%28n-1%29%2F6%29
2%28n-2%29+=+%28n%28n%2B1%29%29%2F2
4n-8+=+n%5E2%2Bn
n%5E2-3n%2B8+=+0

The solutions are not real numbers....
