Question

Which of the following is proper notation to describe the set of all letters in the alphabet?

{a, b, c . . . z}
(a, b, c, etc.)
a through z

Answer 1

`{a, b, c . . . z}` is the best way because it is implied that each letter between c and z is also listed too. The curly braces indicate we have a set of items. In this case, a set of letters.

`(a, b, c, etc.)` won't work because it's not clear how many letters you want or where you stop in the alphabet. Also, this isn't using curly braces that set notation needs

`a through z` doesn't use curly braces, so this doesn't work either

Answer 2

thankyou so much
