Here's another for you stinger

A solo dice game is played thusly: one each turn, a normal pair of dice is rolled. The score is calculated by taking the product, rather than the sum, of the two numbers shown on the dice.

On a particular game, the score for the second roll is five more than the score for the first; the score for the third roll is six less than that of the second; the score for the fourth roll is eleven more than that of the third; and the score for the fifth roll is eight less than that of the fourth. What was the score for each of these five throws?

let the 1st throw be x

2nd......................5x

3rd......................5x-6

4th....................(5x-6)+11

5th....................[(5x-6)+11]-8

The posible outcome for a dice thrown 5 times is :

12 times 5= 60
now, [(5x-6)+11]-8 = 60
        [(5x-6)+11]   = 68

b4 i continue , am i getting somewhere, IG ?

Sort of but not quite. First we must use the information given to compute x

let the first throw be x

possible answers for x:
1x1=1
1x2=2
1x2=3
1x4=4
1x5=5
1x6=6
2x4=8
3x3=9
2x5=10
2x6=12
3x5=15
4x4=16
3x6=18
4x5=20
4x6=24
5x5=25
5x6=30
6x6=36
2nd .................... x+5 so we can look at the chart and take out any equations that won't fit, like if the dice were 1 & 2 the equation would be 1x2+5=7 well there is no two dice when mulitpled can equal seven so our chart removes several and now looks like this.

1x1=1
1x2=2
1x2=3
1x4=4
1x5=5
1x6=6
2x4=8
3x3=9
2x5=10
2x6=12
3x5=15
4x4=16
3x6=18
4x5=20
4x6=24
5x5=25
5x6=30
6x6=36

so you continue Kendan

awww you give up too quickly Kendan.  Yes where is Chris-Jaxx, wonder how he would do here? :)

3rd.......... (x+5)-6 so x-1

We then narrow our possible answers to:

1x1=1
1x2=2
1x2=3
1x4=4
1x5=5
1x6=6
2x4=8
3x3=9

2x5=10
2x6=12
3x5=15
4x4=16
3x6=18

4x5=20
4x6=24
5x5=25
5x6=30
6x6=36

well no, we are not done yet.

4th .......... (x-1) + 11 so x+10

1x1=1
1x2=2

1x2=3
1x4=4
1x5=5
1x6=6
2x4=8
3x3=9

2x5=10
2x6=12
3x5=15
4x4=16
3x6=18
4x5=20
4x6=24

5x5=25
5x6=30
6x6=36


So at this point we know that the first roll (x) is either 5 or 10.  You try the last part Kendan.

No not double answer Kendan, it has just been narrowed to two answers.  I was wanting you to finish the problem and come up with the answer.

5th............. (x+10) - 8 so x+2

So we have eliminated 1x5 as an answer leaving us with 2x5 as the first roll.

1x1=1
1x2=2
1x2=3
1x4=4

1x5=5
1x6=6
2x4=8
3x3=9

2x5=10
2x6=12
3x5=15
4x4=16
3x6=18
4x5=20
4x6=24
5x5=25
5x6=30
6x6=36


So using the given equations and what we computed.

First roll was 10 so a 2 & 5
Second roll was 15 so 3 & 5
Third roll was a 9 so 3 & 3
Fourth roll was 20 so 4 & 5
Fifth roll a 2 so a 1 & 2

Voila!
