Question

Find general and middle terms

Answer 1

⭕️The formula for the general term:-

Tr+1 = (nr)^a^n–r b^r

✔️where 0 ≤ r ≤ n.

➖➖REMEMBER :-
⭕️If you are expanding (x+y)2, then the middle term will be (2/2 + 1) = 2nd term.

⭕️(n2 + 1)th term can also be written as (n+2/2)th term.

⭕️if you are expanding (x+y)3, then the middle terms will be (3+1/2) = 2nd term
and (3+3/2) = 3rd term.
