VR Question - can't figure it out!!

Post by coolmum123 »

Hello all,


My DS justg did test 5 of the learning together VR book 1 and there is a mathsy type question in there and we don't have a clue how the answer has been arrived at!! Can someine help please?


The question is as follows:

Complete these sequences by inserting the correct number in the brackets.

8 27 64 125 ( )

The answer is 216 but we don't know why!!

Also are these books good prep if we are applying to QE, Dr Challoners, Merchant Taylors, Habs, John Lyon? He has finished the book just wondering if it's worth me buying the next book in the series.

Thanks and Regards

Hi coolmum

They are cube numbers ie
2x2x2=8

3x3x3=27 etc

6x6x6=216

Good Luck with your prep

I could do the question, but the thing that puzzles me is why is that Verbal Reasoning? Seems nothing like it to me. Do questions like this come up in the real verbal reasoning? Is it just a sneaky way of testing maths in areas that do not have a maths paper?

hi coolmum

the square series 1,2,4,9,16,25,36,49,64,81,100
and the cube series 1,8,27,64,125,216,343

are worth memorising as they tend to crop up here and there and it can be easier if they just "jump oit" at you

good luck with the papers!

Thx everyone,

was being a bit thick!! I got as far as thinking square numbers?!!!! But didn't go one step further!!!!! Typical.

thx for the tips re other square / cubed no's likely to pop up - will incorporate into prep!! They have to remember loads don't they?!!

Hi perplexed

Mathematical questions appear in verbal reasoning papers because of the "reasoning" that is required to work them out.

Numbers are considered to be part of vocabulary and are therefore "verbal".

Number series questions are not much different to letter series questions in that there is a logical counting forward, counting backward process that uses a specific rule that needs to be identified by the student.
