Question statement

Enumerate each of the following sets.

Note that you input sets in the form set(a,b,c,..,z) .

For example set(1,2,3)gives the set $\{1,2,3\}$ .

The empty set is input as set().

Also some labour saving tips:

If you want to input all integers between $a$ and $b$ inclusive then instead of writing all the elements you can input this as set(a..b).

If you want to input all integers between $a$ and $b$ inclusive in steps of $c$ then this is input as set(a..b#c). So all odd integers from $-3$ to $28$ are input as set(-3..28#2).

Give any introductory information the student needs.

Gap-fill

Ask the student a question, and give any hints about how they should answer this part.

1) $S=\{y\;|\;y \in \mathbb{Z}, y=\var{a}x-\var{c},\;x \in \mathbb{Z}\text{ and } |y| \leq \var{b}\}$

$S\;$ =Gap 0.

2) $S=\{y\;|\;y \in \mathbb{N}, y=\var{a}x-\var{c},\;x \in \mathbb{Z}\text{ and } |y| \leq \var{b}\}$

$S\;$ =Gap 1.

3) $S=\{x\:| x \in \mathbb{Z}\text{ and }\;|\var{a1}x-\var{c1}| \leq \var{b1}\}$ .

$S=\;$ Gap 2.

4) $S=\{x\:| x \in \mathbb{N}\text{ and }\;|\var{a1}x-\var{c1}| \leq \var{b1}\}$ .

$S=\;$ Gap 3.
