Find the rates of change until it is constant...

dy/dx=7,16,25,34,43

d2y/dx2=8,9,9,9 so it appears 8 is the anomaly while the acceleration constant is 9 after the initial term. Let's set up a system ignoring the first data point and solve for the quadratic...

16a+4b+c=50
9a+3b+c=25
4a+2b+c=9 gettting differences

7a+b=25
5a+b=16 and again

2a=9, a=4.5, making 5a+b=16 become:

22.5+b=16

b=-6.5, making 4a+2b+c=9 become:

18-13+c=9, c=4

So the sequence can be expressed as:

a(n)=4.5n^2-6.5n+4, where n=term number

Nikki has 3 pieces of yarn. the first piece is 5/6 feet long the second piece is 5/3 feet long and the third piece is 3/2 oder s

I think you are asking to sort them according to the shortest to longest in length. For this, it would be helpful to write the fraction into decimal. The equivalent values are as follows:

5/6 = 0.83
5/3 = 1.67
3/2 = 1.50

Therefore, the correct sorting would be as follows:

first yarn
third yarn
second yarn

Hope this answers the question. Have a nice day.
