Answer:

D)64, 128, 256, 512, 1024, 2048

Step-by-step explanation:

A geometric sequence is defined by the recursive formula t1 = 64,

t_n = t_{n - 1} \cdot 2

To get the geometric sequence , plug in the value for n=2,3,4,5....

n=2, plug in 2 for n

t_2 = t_{1} \cdot 2

t_2 = 64 \cdot 2=128

n=3, plug in 3 for n

t_3 = t_{2} \cdot 2

t_3 = 128 \cdot 2=256

n=4, plug in 4 for n

t_4 = t_{3} \cdot 2

t_4 = 256 \cdot 2=512
