[" 3.If "A={x:x=4n+1,2<=n<=5}" ,then number of subsets of "],[A" is "]

If A={x:x=4n+1,2<=n<=5,n varepsilon N}, then the number of subsets of A is :

If A={x:x=3^(n)-2n-1, n in N} and B={x:x = 4(n-1), n in N} . Then

If A={x:x=3^(n)-2n-1, n in N} and B={x:x = 4(n-1), n in N} . Then

Find the number of subsets of A if A = { X : X = 4n +1, 2 lt= n lt= 5, n in NN }

Which of the following sets are equal ? A= {x:x in N,x <4), B= {1,2, 3}, C={1 ,3}, D = {x:x in N, x is odd, x < 5}, E= {1,2, 3, 2}, F = {3,3,1}.

The set (0,2,6,12,20) in the set-builder form is (1) {x:x=n^(2)-3n+2," where "n'" is a natural number "&1 (2) {x:x=n^(2)-3n+2," where "'n'" is a natural number "&1 (3) {x:x=n^(2)-3n+4," where "'n'" is a natural number "&1 (4) {x:x=n^(2)+5n-6," where 'n' is a natural number "&1<=n<=5}

If ((1 +i)/(1 -i))^(x) =1 , then (A) x=2n+1 (B) x=4n (C) x=2n (D) x=4n+1, n in N.

If ((1 +i)/(1 -i))^(x) =1 , then (A) x=2n+1 (B) x=4n (C) x=2n (D) x=4n+1, n in N.
