Expansion of (1 + x) 5 has 6 terms, so 3rd and 4th both are middle terms . Illustration : Find the middle term in the expression of (1 − 2x + x 2) n Solution : (1− 2x + x 2) n = [ ( 1 − x) 2] n = ( 1− x) 2n Here 2n is even integer, therefore, (2n/2 + 1) th
WebThe constant term in the expansion of ( x − 1 x) 10 is: Q9. If the coefficients of x2 and x3 in the expansion of (3 + ax)9 are the same, then the value of a is: Q10. If in the expansion of (1 + x)20, the coefficients of rth and (r + 4)th term are equal, then r is equal to: More Binomial Theorem Questions Q1. WebAn expansion x - 1 x 18 is given. The number of terms in the expansion is 18 + 1 = 19. The middle term of the expansion is given by 19 + 1 2 = 10. That is T 10 is the middle term of the given expansion. Compute the value of T 10 as follows: T 10 = C 9 18 · ( x) 9 - 1 x 18 - 9 ⇒ T 10 = - C 9 18 · ( x) 9 1 x 9 ⇒ T 10 = - C 9 18
WebCompute the middle term of the given expansion. An expansion x-1 x 18 is given. The number of terms in the expansion is 18 + 1 = 19. The middle term of the expansion is … WebNov 13, 2024 · Given If the middle term in the expansion of (x^2+1/x)^n is 924x^6 then n = There is one middle term. So let middle term be n/2. Now middle term will be n C n/2 (since r will be middle term) So n Cn/2 (x^2) ^n – n/2 (1/x)^n/2 So n Cn/2 x x^2n/2 . 1/x^n/2

WebMiddle Term: The total number of terms in the expansion of (x + y) n is equal to n + 1. The middle term in the binomial expansion depends on the value of n. The middle term and the number of middle terms depend on the value of n: n is even or odd. For an even value of n there is only one middle term and (n/2 + 1) th term is the middle term. For ... k3 ケルヒャー 楽天WebHence, 𝑛 = 1 2 or 𝑛 = − 1 1. The binomial theorem only applies for the expansion of a binomial raised to a positive integer power. Therefore, 𝑛 must be a positive integer, so we can discard the negative solution and hence 𝑛 = 1 2.
