Find an equation that fits into coordinates.

Hey all

If i have some coordinates that are: (1,1) ; (2,10) ; (3,3) ; (4,12) ; (5,5) ; (6,14) etc.

How to find the equation that fits into that?

Thanks in advance

The data have the form (n, n + 4 + 4(-1)^n), where n = 1, 2, 3, 4, 5, 6, etc.

It depends. The most obvious I can see is



to give you the pairs but there are infinitely many possibilities (for example

Okay, got it - it fits in perfectly! Now a second problem arises. It is related to this problem, but it will take to long to explain why.

The second problem is as follows:

if then
if then
if then

How to find the function that fits?
Any suggetions?

The simplest possibility is y = (x - 16)/2.
