Answer:

{16, 17, 18, 19} are the numbers.

Explanation:

If n stands for a whole number and 2n is greater than 30.

Means 2n > 30

⇒ n > 15

Now another statement says 5n is less than 100

Means 5n < 100

⇒ n < 20

So n defines the values

20 > n > 15

If n is a whole number then numbers between 15 and 20 will be

{16, 17, 18, 19}. This set will not include 15 and 20 since n is not equal to these numbers.
