Question

I need help plz pt.2​

Answer 1

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.
