Which term will be the middle term of (xyz – x)^2n?(a) (n + 1)^th term(b) (n + 2)^th term(c) n^th term(d) (n – 1)^th termI had been asked this question during an online exam.My question is from Binomial Theorem topic in chapter Binomial Theorem of Mathematics – Class 11

Answer»

The CORRECT OPTION is (a) (n + 1)^th term

The best explanation: Clearly 2n is an EVEN number and the BINOMIAL has 2n + 1 terms.

The middle term for a binomial with even power, is the term equal to (n/2 + 1) where n is number of terms.

In this case,(2n/2 + 1) = n + 1.
