Question

Classify the following sets as finite, infinite and null sets.
(a) X = { x | x+3 = 1, x € N }

(b) X= { x | x + 5 = 5, x € W }

(c) y = { x | 2x < 5₁ x € Z }

(d) Z= { y| y=n², n = N }

(e) A = { x | x < 5, x € W }

(f) B ={ y | y²= 4, € N }

please tell me right answer​

Answer 1

Answer:

{x:x=5n,n∈W and x<60}

={5,10,15,20,25,30,35,40,45,50,55}

It is finite set and it has 12 elements
