#### Bradley Bush commented on Identifying different types of sequences7 years ago

Thank you for the feedback Christian:

• I have added tables to the feedback for parts and b to make the working easier to follow.
• I have added a table to the feedback for c also to analyse the difference between terms but I have included Hannahs solution using the formula as an alternative method of solving this.
• I have altered question d to be the more generic randomisable sequence equation which you suggested.
• I attempted to explain the solution using a table here to find the differences too but I am not too sure how thoroughly this would explain the way you work out that the sequence is squared numbers and cubic numbers without simply recognising them. Nor am I confident I even know how to recommend solving this problem if you do not recognise the squared or cubic terms on your own?

Thank you for the feedback Christian,

• There was a slight error with the gap fills so I fixed that
• There was another error with the answer marking, so that's fixed too
• I've adjusted the advice as you recommended to include a table, but I've also left Hannah'smethod as an alternative, I'm not sure whether yu wanted it completely replaced or no so I've left it in.
