Saved a checkpoint:

I've vastly rewritten the advice, and given the variables sensible names.

It would be good to have another version of this question where you fill in the table first.

I don't think this question is worth saving. I've split part d, about finding a given term, into a separate question.

Ideally, there'd be a question combining parts a and b, asking you to sort a few sequences into linear, quadratic, geometric, or other. 

I don't think there's any point in the parts which ask you to give the next three terms of the triangle, square, and cube numbers.

Chris Graham on Exponential increase 8 years, 4 months ago

Gave some feedback: Needs to be tested

Chris Graham commented on Exponential increase 8 years, 4 months ago

I have changed "percentage multiplier" to "decimal multiplier" in the step and advice. Also changed the advice so that the percentage change is calculated first. Asking the student to multiply by 100 then subtract 100 in one step meant that they skipped completely the idea of, say, a 108% change in the value. 

I've removed some variables which were strange / not required.

I've tidied up the text, and gone to town on the variables because they were crazy.

I have reworded the advice as per my own suggestion.

This was a bit of a mess, as the points A and B had originally been illogically ordered, and this had only been half fixed. 

Part a) had mathematical expression gaps which should have been number entry, and I have added fractionNumbers simplification in the advice and displayed answer.

I've adjusted the axis ranges so that the intercept is always on the grid.

I've added some context to the question.
