Can anyone tell me what is the equation for First Order of(adsbygoogle = window.adsbygoogle || []).push({}); Newton’s Interpolation?

The one of Interpolation I know isLagrange’s Interpolationsuch as

[tex]p(x)= \frac {x-x1}{x0-x1} f(x0) + \frac {x-x0}{x1-x0} f(x1)[/tex]

and so on ...

Thanks in advance
