log1/49 ?

-----------You want to know log of 7. It would be somewhere between log of 5 and log of 8. You might like to try linear interpolation.

    input      |     log of input
               |
               |
----------------------------------------
    5          |          0.7
    7          |         log((7))=y
    8          |          0.9
----------------------------------------

y=mx+b
