Find the middle term in the binomial expansion of…
The sum of the real values of x for which the middle term in the binomial expansion of (x 3 /3 + 3/x) 8 equals 5670 is? Hence, the middle term = t 11. In this case, we replace “r” with the two different values. These middle terms will be (m + 1) th and (m + 2) th term. $$ k = \frac{n}{2} + 1 $$ we do not need to use any different formula for finding the middle term of. To find the middle term: Hence, the middle terms are :. In simple, if n is odd then we consider it as even. Locating a specific power of x, such as the x 4, in the binomial expansion therefore consists of determining the value of r at which t r corresponds to that power of x. Such formula by which any power of a binomial expression can be expanded in the form of a series is.
A + x, b = 2y and n = 9 (odd) First, we need to find the general term in the expansion of (x + y) n. We have 4 terms with coefficients of 1, 3, 3 and 1. ∎ when n is even middle term of the expansion is , $\large (\frac{n}{2} + 1)^{th} term $ ∎ when n is odd in this case $\large (\frac{n+1}{2})^{th} term $ term and$\large (\frac{n+3}{2})^{th} term $ are the middle terms. N is the power on the brackets, so n = 3. The index is either even (or) odd. Two cases arise depending on index n. The number of terms in the expansion of (x + a) n depends upon the index n. ⇒ 70 x 8 = 5670. Hence, the middle terms are :. T 5 = 8 c 4 × (x 12 /81) × (81/x 4) = 5670.
