I don’t understand what this is saying? The binomial coefficients of the terms which are equidistant from the starting and the end are always equal. The simple reason behind this is C(n, r) = C(n, n-r) which gives C(n, n) C(n, 1) = C(n, n-1) C(n, 2) = C(n, n-2).

Means first binomial coefficient = last binomial coefficient
2nd binomial coefficient =2nd last binomial coefficient

and so on

Thanks
