Then what was the growth rate?

=RATE(6,, -10, 100)

That is the average __quarterly__ rate.

If you want the effective __annual__ rate, ostensibly,
it might be:

=FV(RATE(6,, -10, 100), 4,, -1) - 1

which is the same as (1 + r)^4 - 1, where "r" is the
quarterly rate, however you want to compute it.
