A geometric sequence is defined by the recursive formula
t1 = 64, tn= tn-1/2 where n ∈N and n > 1. The sequence is
A)-64, -16, -8, -4, -2, -1, ...
B)64, 16, 8, 4, 2, 1, ...
C)64, 32, 16, 8, 4, 2, ...
D)64, 128, 256, 512, 1024, 2048, ...
The answer is C :)

correct, though your notation makes it unclear. Better would be
t_n = t_n-1 / 2
or
t_(n) = t_(n-1) / 2
t(n) = t(n-1)/2
or t(n) = (t(n-1))/2
sometimes parens or spacing make your intentions clearer
t_n = t_n-1 / 2
or
t_(n) = t_(n-1) / 2
t(n) = t(n-1)/2
or t(n) = (t(n-1))/2
