the growth from 77 - 96 = 7328-78 = 7250
growth factor = 7250/78 = 92.9

7328 = 78(1 + (r/100))^(96 - 77)
(7328/78) = (1 + (r/100))^(19)
(3644/39) = (1 + (r/100))^(19)
ln(3644/39) = 19ln(1 + (r/100))
(ln(3644/39))/(19) = ln(1 + (r/100))
e^((ln(3644/39))/19) = 1 + (r/100)
(r/100) = e^((ln(3644/39))/19) - 1
r = 100(e^((ln(3644/39))/19) - 1)
r = about 26.97%
ANS : about 26.97%

Depends on whether it was linear, exponential, logarithmic, or power series growth.
