How To Find The Middle Term Of A Binomial Expansion

how to find the middle term of a binomial expansion

GENERAL AND MIDDLE TERMS IN BINOMIAL THEOREM

Here we are going to see how to find the middle terms in binomial theorem. General term : T (r+1) = n c r x (n-r) a r. The number of terms in the expansion of (x + a) n depends upon the index n. The index is either even (or) odd. Let us find the middle terms. Case (i) : n is even The number of terms in the expansion is (n + 1), which is odd. Hence, there is only one middle term and it is given

determine the coefficient of the middle term in the

Binomial Expansion To expand an expression like (2x - 3)5 takes a lot of time to actually multiply the 5 brackets together. Instead we use a fast way that is based on the number of ways we could get the terms x5, x4, x3, etc. and is calculated as follows. Write down (2x) in descending powers - (from 5 to 0) Write down (-3) in ascending powers

Example 12 Coefficient of middle term in (1 + x)2n is equal

Transcript. Example 12 Show that the coefficient of the middle term in the expansion of (1 + x)2n is equal to the sum of the coefficients of two middle terms in the expansion of (1 + x)2n – 1.

how to find the middle term of a binomial expansion

Middle Term in Binomial Expansion Binomial Theorem

That means the middle term will have x raised to the n power. Using the binomial theorem, the nth power of x could be achieved [math]\dbinom{2n}{n}[/math] ways. Since the constant and the x coefficient are both 1, that means we just take the number of ways times 1.
