It may be obvious to you that 1^2=2 (surely not ?), 2^2=4 and 3^2=9, but
to me your pairs look like they were derived from the function f[x]=x+x!
(that is Factorial[x], not an x followed by an expression of surprise).
But I could not find a Mathematica function to support my argument - or
to support yours for that matter.
I guess you could try Fit and its related functions ...
