Question

if n is even in any Binomial expansion then how many middle terms are there in the expansion​

Answer 1

Answer:

There is two middle terms which are t(n+1/2) &t(n+3/2)

Answer 2

Answer:

1

Step-by-step explanation:

When you are trying to expand (a+b)n and ‘n’ is an even number, then (n + 1) will be an odd number. Which means that the expansion will have odd number of terms. In this case, the middle term will be the (n/2 + 1)th term.

For example, if you are expanding (x+y)2,. (n/2 + 1)th term is also denoted as (n+2/2)th term.
