Question

Write the following set using listing method and classify into finite or infinite set. B = { x|x ∈ N and 3x – 1 = 0 }
​

Answer 1

Answer:

1) A = (1,3,5,7,9....)

It is a infinite set.

2) Let x = Natural number

x = 1 thn, 3(1) - 1 = 3 - 1 = 2

x = 2 thn, 3(2) - 1 = 6 - 1 = 5

B = ( )

It is a finite set.

3) x = (natural number divisible by 7)

if x = 14 thn, 14 is divisible by 7 we get 2.

Thus it is a infinite set.
