Answer:

See explanation

Explanation:

Consider the sequence
$(1)/(32),\ (1)/(8),\ (1)/(2), 2,\ 8,...$

Rewrite it as

$b_1=(1)/(32),\\ \\b_2=(1)/(8),\\ \\b_3=(1)/(2),\\ \\b_4=2,\\ \\b_5=8...$

The points on the coordinate plane are

$(1,b_1),\ (2,b_2),\ (3,b_3),\ (4,b_4),\ (5,b_5),...$ (see attached graph).

Since

4=(b_2)/(b_1)=(b_3)/(b_2)=(b_4)/(b_3)=(b_5)/(b_4)..., given sequence is geometric.
