Question

What is the formula of mid term?​

Answer 1

Answer:

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.
