If `X={4^(n)-3n-1 : n in N}` and `Y={9(n-1) : n in N}`, then

If X = {4 ^(n)-2n-1: n in N} and Y={9(n -1) : n in N}, then Xnn Y=

If X ={(4^(n) -3n -1) | n in N] and Y= {9(n-1)| n in N} , then X cup Y equals to

If X={4^(n)-3n-1n in N} and Y={9(n-1):n in N} , then X uu Y is equal to

If X={4^(n)-3n-1:n in N} and Y={9(n-1):n in N} ,where N is the set of natural numbers,then X uu Y is equal to (1)N(2)Y-X(3)X(4)Y

If X={8^(n)-7n-1:n in N) and Y={49(n-1): n in N}, then

If X={4^(n)-3n-1:n in N} and {9(n-1):n in N} , the prove that X sub Y .

If X={8^(n)-7n-1,n in N} and Y={49(n-1);n in N}, then prove that X is a subset of Y

If X={8^(n)-7n-1,n in N} and Y={49(n-1):n inN}, then prove that X sube Y .

If A={4^(n)-3n-1:n in N) and B={9(n-1):n in N} then
