```Hello,

First, suppose I have two real values

year               earnings
x = 3              f(x) =   20
x= 10             f(x) =   50

I want to have the interpolated values of f(4), f(5), to f(9) which is between actual values of f(3) and f(10). How can I do that with Mathematica?

Second, suppose I have an excel spreadsheet having those above values for multiples firms as of the following

firm      f(3)       f(10)
A          20        50
B          30        55
C          60        25

I want to have the values of f(4) till f(9) as above and are stored in excel spreadsheet as of the following:

firm      f(3)     f(4)    f(5)  ...    (f9)      f(10)
A          20                                            50
B          30                                            55
C          60                                            25

Best Regards,
Kosal
