I've fixed the advice for parts b and c  the power should be $n1$, not $n$.

In part b does not accept correct answer. Mistake also shown in the solutions.

Splitting into 3 questions with 3 parts each instead of 3 parts with 3 gaps
Christian LawsonPerfect 4 years, 2 months ago
And like the other sequences questions, the advice would benefit hugely from a table.

Saved a checkpoint:
The gaps are all set as "mathematical expression", but there's no reason they shouldn't be "number entry" (apart from the formula part, obv.)
The parts of this question aren't coherent; you could keep the same sequence throughout, and ask the student to:
 Find the common ratio
 Give the formula for the $n$th term
 Calculate a given term.

 Make sure i) and ii) etc are in italics both in the parts and the advice.
 I think I would capitalise "Common ratio" in part a).
 Advice content for a) is fine.
 Where you have stated what the formula for the geometric sequence is in part b) of the advice, I think you should explain that a is the first term and r is the common ratio.
 Make sure you use displaystyle to make the formula large.
 Think there might be a slight glitch in the advice of c) where you are trying to figure out the common ratio, it says a[3]*a[4]^3 instead of 375 as it was supposed to be in this case.
 Typo in the last sentence of the advice  it says "we can write substitute them into the formula..."  "We" should be capitalised and just scrap write.

It would also be helpful to give and exlain the formula for the $n$th term in the statement.

Vicky Hall 4 years, 2 months ago
I have added a sentence to the statement to explain what is meant by the common ratio. I think part a) should include one sequence with a positive integer ratio, one with a negative integer ratio and one with a fractional ratio to cover all possibilities.

When you need to change the way this part works beyond the available options, you can write JavaScript code to be executed at the times described below.
To account for errors made by the student in earlier calculations, replace question variables with answers to earlier parts.
In order to create a variable replacement, you must define at least one variable and one other part.
Variable  Answer to use  Must be answered?  

The variable replacements you've chosen will cause the following variables to be regenerated each time the student submits an answer to this part:
These variables have some random elements, which means they're not guaranteed to have the same value each time the student submits an answer. You should define new variables to store the random elements, so that they remain the same each time this part is marked.
This part can't be reached by the student.
Add a "next part" reference to this part from another part.
None of the parts which can lead to this part are reachable either.
