Re: Maths questions please
19?
Start at 1
Next 2 numbers go up by 0
Then next 2 numbers go up by 3
So the next 2 numbers go up by 6 - 13 & 19

Re: Maths questions please
I think it is:Walthams wrote:Hello,
Question 26 from Habs 2011 paper asks to find the next number in this sequence:
1 1 1 4 7 13 _ .
What is the rule for this sequence? I know what the answer should be but don't know why... Could anyone help with this? Thanks.
Total of previous numbers; then total of previous numbers minus one; then total of previous numbers plus one; repeat.
So total of 1=1.
1+1-1=1
1+1+1+1=4
1+1+1+4=7
1+1+1+4+7-1=13
1+1+1+4+7+13+1=28
Fiendish though.
Re: Maths questions please
This is not a proper rule though. Where is the 'answer' posted? Is there a link to the paper please?

Hi All
Could someone please help with this
Question
I bought a packet of fruit gums and ate 2 of them, secretly , in my Music lesson.
At break , I shared one third of the remaining fruit gums with my friends, I then finished the fruit gums, eating an equal amount in each of the next four lessons.
What is the smallest number of fruit gums there could have been in the packet?
here's my approach and I think not correct. then I get stuck?
packet of fruit gum = x no of fruit gums
(x-2) =remaining fruit gums
(x-2)/3 = number shared
thanks

Re: Maths questions please
After sharing with a friend, I'm left with 2(x-2) / 3 of the sweets
I then have a quarter of the remaining amount in each of the next 4 lessons, so I have 2(x-2) / (3x4), or (x-2) / 6 in each lesson.
The smallest number of sweets I ate in each of the last 4 lessons is 1, so the smallest value for x must be 8.
