The 3rd Term Is 24 ---> ar^2 = 24
The 5th Term Is 3 ---> ar^4 = 3
divide them
r^2 = 3/24 = 1/8
r = 1/2√2
a(1/64) = 24
a = 24*64 = ...
now form your terms

r^2 = 3/24 = 1/8
r = 1/√8 = √2/4
ar^2 = 24
a = 24*8 = 192
So the sequence is
192, 48√2, 24, 6√2, 3, ...
r = 1/√8 = √2/4
ar^2 = 24
a = 24*8 = 192
So the sequence is
192, 48√2, 24, 6√2, 3, ...
