Hi! The given expansion is . General term of the given expansion, Here n = 10, which is even. So, th term i.e., 6^{th} term is the middle terms of the given expansion. Putting r = 5, we get Thus, the middle term in the given expansion is –252. Cheers! Posted by Lalit Mehra(MeritNation Expert)on 30/11/11 This conversation is already closed by Expert
