If A = `{3n + 5 : n in N and n le 6}`, then represent set A I the roster form.

A={x:x in N " and 5 lt x le 6}

If A = { x : x = 3n-1, n in N and n le 5 } B = { x : x is an odd natural number and x lt 15 } and C = { x : x =4n , n in N and n lt 7 } ,find B cap C

If A = { x : x = 3n-1, n in N and n le 5 } B = { x : x is an odd natural number and x lt 15 } and C = { x : x =4n , n in N and n lt 7 } ,find A cup B

If A = { x : x = 3n-1, n in N and n le 5 } B = { x : x is an odd natural number and x lt 15 } and C = { x : x =4n , n in N and n lt 7 } ,find A cap B

If A = { x : x = 3n-1, n in N and n le 5 } B = { x : x is an odd natural number and x lt 15 } and C = { x : x =4n , n in N and n lt 7 } ,find A cap B

If A = { x : x = 3n + 2 , n in N , n le 6} B = { x : xis an even number natural number 4 , lt x lt 15 } and C = { x: x = 3n , n in N , n lt 8 } then find (i) A cup B (ii) A cap B (iii) A cap C (iv) B cap C Also find whether the sets A and B : A and C, B and C are disjoint or overlapping sets .

If a N = { ax : x in N} then the set 4N cap 6N is

If A = {1,2,3,4,5} and B = {4,5,6,7,8} , then deduce the result for these sets : n(A cupB)=n(A)+n(B)-n(AcapB) .

If n(A) = 10,n(B) = 6 and n( C ) =5 for three disjoint sets A,B,C then n (A cup B cup C) equals

If X = {1,2,3} , if n represents any member of X, write the following sets containing all numbers represented by (i) 4n , (ii) n +6 , (iii) n/2 , (iv) n - 1
