If the middle term of `(1+x)^ (2n)` is `(1.3.5….(2n-1)k)/(n!)` then `k=`

The middle term of (x-1/x)^(2n+1) is

The middle term of (x+(1)/(x))^(2n) is

The middle term of (x-(1)/(x))^(2n+1) is

Show that the middle term in the expansion of (1+x)^(2n) is (1.3.5….(2n-1))/(n!) 2^(n)x^(n) , where n is a positive integer.

If the middle term in the expansion of (1 + x)^(2n) is (1.3.5…(2n - 1))/(n!) k^(n).x^(n) , the value of k is

Show that the middle term in the expansion of (1+ x)^(2n) is (1.3.5…(2n-1) )/( n!). 2^(n) . x^(n) , where n in N .

If the middle term in the expreansion of (1+x)^(2n) is ([1.3.5….(2n-1)])/(n!) (k) , where n is a positive integer , then k is .

Show that the middle term in the expansion of (1+x)^(2n) is 1.3.5…(2n-1)/n! 2n.x^n , where n is a positive integer.

Prove that the middle term in the expansion of (x+ 1/x)^(2n) is (1.3.5…(2n-1)/(n! 2^n

Show that the middle term in the expansion of (1+x)^(2n) is (1.3.5...*(2n-1))/(n!)2nx^(n)2nx^(n) where n is a positive integer.
