Question

{x:X=3n-2,n€W,n greater than equal to 8} find the Cardinal number​

Answer 1

Answer:

Step-by-step explanation: P = {x : x = 3n+2, n∈W and x< 15}

For x < 15, n ∈ W :

3n + 2 < 15

3n < 15 - 2

3n < 13

n < 13/3

n < 4.3

Since n has to a natural number, n can only be 1, 2, 3 or 4

⇒ There are 4 elements

Answer: n(P) = 4
