Express the following in roster form:

Set M is the set of natural numbers between fourteen and nineteen.

I don't have a clue what you mean by "roster form", never heard that expression.

Usually N is used to describe the set of natural numbers.

I would write your set as
{x | 14 < x < 19, x ∈ N}

yea i was stuck on this one too....thank you though

To express the set M in roster form, we need to list all the natural numbers between fourteen and nineteen.

M = {15, 16, 17, 18}

Therefore, the set M in roster form is {15, 16, 17, 18}.

To express the set M in roster form, we need to list all the natural numbers that are between fourteen and nineteen.

The natural numbers between 14 and 19 are 15, 16, 17, and 18.

Therefore, the set M, expressed in roster form, is:

M = {15, 16, 17, 18}
