First, we will find the common difference
The common difference is ;
19 - 11 = 8
or
11 - 3 = 8
common difference is 8
As the position increase by 1, the result increase by 8
so we will keep on adding 8 to the result
Position Result
4 19
5 27
6 35
7 43
8 51
Hence;
when the position is 8, the result is 51
This would be 42 because 17+4•2=42
Each glass will get 1 7/9 of a cup because a Fallon is 16 cups and 16÷9=1.77777777778, which in fraction from is 1 7/9. I can justify my answer because 1 7/9×9=16. Good Luck!
52.8 because 5,280/100=52.8
So the knot is 52.8
