Question

formula for middle most term of odd and even​

Answer 1

Step-by-step explanation:

• Middle Term in the Binomial Theorem:

Let us now find the Middle Terms in our binomial expansion: (x + y)n  

Two cases arise depending on index n.

Case 1: when n is odd:

There are two middle terms in Binomial Theorem.

One is T( n + 1)/2 and the other is T( n + 3)/2

Case 2: when n is even:

When the binomial index n is even, we can see there is only one middle term. And it is T( n/2 + 1).
