There will be an infinite number of “patterns” that fit only 3 points. 3 points can determine a circle or parabola. If you need this to be a function, you can use a quadratic function or a class of higher-order polynomials.
For finding the quadratic to fit these 3 numbers, take the first & second differences:
7…14…23
…7…9
……2…..
Divide the second difference by 2! (2nd-degree equation) to get the leading coefficient: 1. This gives you the equation
y = 1*x^2 + b*x + c. You should now be able to solve for b & c, using the given points. That gives you one equation.
Does that get you started?
