`2^(n).1.3.5.7....(2n-1)` का मान है

Show that the middle term in the expansion of (x-1/x)^(2n) is (1.3.5.7....(2n-1))/(n!)(-2)^n

The value of 1 + 3 + 5 + 7 +……………. (2n - 1) is: 1 + 3 + 5 + 7 +……………. (2n - 1) का मान है:

The value of [0.9-{2.3-3.2-(7.1 - 5.4 - 3.5)}] is: [0.9-{2.3-3.2-(7.1 - 5.4 - 3.5)}] का मान है :

The value of 1 + 3 + 5 + 7 + ……………. (2n - 1) is: 1 + 3 + 5 + 7 + ……………. (2n - 1) का मान है:

3(1)/(12)-[1(3)/(4)+{2(1)/(2)-(1(1)/(2)-(1)/(3))}] का मान है -

If n is a natural number then show that 1.3.5.7…..(2n-1) = ((2n)!)/(2^n n!)

The A.M.of the observations 1.3.5,3.5.7,5.7.9,......,(2n-1)(2n+1)(2n+3) is (AA n in N)

Prove that by using the principle of mathematical induction for all n in N : 1.3+3.5+5.7+....+(2n-1)(2n+1)= (n(4n^(2)+6n-1))/(3)

Prove that by using the principle of mathematical induction for all n in N : 1.3+3.5+5.7+....+(2n-1)(2n+1)= (n(4n^(2)+6n-1))/(3)
