The awnser can be obtained by doing the following:
Multiply the numer of kaus with the days they take to eat all of the grass for both of the days
then calculate the difference between those two numbers..
Calculate the difference between the days
then calculate by what factor the days have to decrease (looking from the lowest day) to reach 16
take the same factor from the calculated difference from the kau x day numbers
take that factor of the difference and part that number by the number of asked days then you should end up with a number of kaus
Could the answer be 250 here's what I did. The middle represents the number added by 32. I got that by subtracting 48 from 16. The third row is the estimated. It goes by 30. You'll understand the first by looking at the question and the diagram.
2=32=30
4=64=60
6=96=90
8=128=120
10=160=160
12=192=190
14=224=220
16=256=250
looks like u didn factor in the growth...
Did anyone else try logarithms? The hint I used was "the grass grows continuously".
but the thing is it that the middle is what grows. and the third represents the estimated of grass that grows.
I used a simple inverted 3 rule..
something like
100 - 10
50 - 20
x - 30
its 168 when rounded up.
you get the answer using basic course 2 algebra. I set up 2 equations espressing the rates of which the kau ate and the grass grew.
the equations looked like this:
Let K = rate at which Kaus eat grass
Let G = rate at which grass grows
Let 1 = the fact that the field is already full of grass
1 = 48*90K - 90G
1 = 120*30K - 30G
This is a simple matter of solving linear equations. I multiplied the bottem equation by -3 getting
-3 = -360*30k + 90G
I then added the equations together to drop out the G variable.
I solved for K.
K approxis for .000617284.
Plug K in the original equation to solve for G.
G approxis for .0407407
Now that you know the rate at which grass grows and the rate 1 kaus eats grass, you can now make a new equation.
Let H = number of kaus that will eat all grass in 16 days
1 = .0098765*H - 16*.0407407
Solve for H to get 167.18 Kaus
The directions say to round up to the nearest Kaus (it says Up specifically to ignore the 4 and down rule)
Giving you 168 Kaus!

at 314,the answer is pi related.
3 is the fist number.
1+4 =5,the second number.
1+5+9=16,the third.

49 and 40 comes after the sequence.
49 x 40 = 1960
