THE BINOMIAL THEOREM
How To Find The Middle Term Of A Binomial Expansion - How To Find. Here n = 4 (n is an even number) ∴ middle term =\(\left(\frac{n}{2}+1\right)=\left(\frac{4}{2}+1\right)=3^{\text{rd}} \text{ term }\) $$ k = \frac{n}{2} + 1 $$ we do not need to use any different formula for finding the middle term of.
THE BINOMIAL THEOREM
If n is an even number then the number of terms of the binomial expansion will be (n + 1), which definitely is an odd number. The binomial expansion is ( a + b) n = ∑ r = 0 n c ( n, r) a n − r b r. To find a particular term of an expansion, we can use the formula given below. If n is odd, then the two middle terms are t (n−1)/ 2 +1 and t (n+1)/ 2 +1. ⇒ x = ± √3. Consider the general term of binomial expansion i.e. Binomial expansion for positive integral index; Comparing with (a + b) n, we get; = 20 c 10 x 10. In simple, if n is odd then we consider it as even.
Two cases arise depending on index n. A + x, b = 2y and n = 9 (odd) Comparing with (a + b) n, we get; The expansion has 8 terms so what would be the middle term? We have a binomial to the power of 3 so we look at the 3rd row of pascal’s triangle. Let’s say you have (a+b)^3. Let us now find the middle terms in our binomial expansion:(x + y)n. ⇒ 70 x 8 = 5670. Let us see how to find the middle term. Two cases arise depending on index n. In this case, the general term would be:
