Binomial Theorem Formula – Middle Term. 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 ( \frac {n}{2} + 1)th term.
Middle Term of the Binomial Expansion. As we know, the expansion of (a + b)n contains (n + 1) number of terms. Based on the value of n, we can write the middle term or terms of (a + b)n. That means, if n is even, there will be only one middle term and if n is odd, there will be two middle terms.
