=(294.1/286.6)^(12/5) - 1

or

=(294.1/286.6 - 1)*12/5

The right answer depends on whether or not you expect the growth to
compound (first formula).

You cannot do "^2" or "*2", as you might expect, because you really
have only 5 months of changes. It would be great if you have the data
for 12/1/58. Then substitute its value for 286.6 in the denominator
and use "^2" or "*2".
