Description

Describe what this variable represents, and list any assumptions made about its value.

Can an exam override the value of this variable?

Generated value: `list`

[ 13, 3, 11 ]

This variable doesn't seem to be used anywhere.

Gap-fill

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

For an insight into negative indices, consider the following table:

index form	$\var{base}^3$	$\var{base}^2$	$\var{base}^1$	$\var{base}^0$	$\var{base}^{-1}$	$\var{base}^{-2}$
result	$\var{base^3}$	$\var{base^2}$	$\var{base}$	$1$	Gap 0.	Gap 1.

Notice each time the power decreases by $1$ , the result is divided by $\var{base}$ . Using this idea, and / for division, fill in the rest of the table.

Advice

Give a worked solution to the whole question.
