Solution:
Since, rth term from the end in the expansion of a binomial (r +)n is same as the (n - r +2)th term from the beginning in the expansion of same binomial.
So, the required ratio is.
A ratio of the 5th term from the beginning to the 5th term from the end in the binomial expansion of
Since, rth term from the end in the expansion of a binomial (r +)n is same as the (n - r +2)th term from the beginning in the expansion of same binomial.
So, the required ratio is.
