MIDDLE TERM(S) IN THE BINOMIAL EXPANSION
MIDDLE TERM(S) IN THE EXPANSION OF (x + a)n The number of terms in the expansion of (x + a)n is (n + 1) If n is even If n is odd The no. of terms in the expansion is odd The no. of terms in the expansion is even The largest Binomial coefficient(s) occurs in the middle term(s) only.
