Question

Let me know the answer plz

Answer 1

The correct answer option is B.
`1`,
`(1)/(2)`,
`(1)/(4)`.

Explanation:

We are given the following geometric sequence and we are to find its 8th term:

`16, 8, 4, 2,...`

Here
`a_1=16` and common ratio
`(r) = (2)/(4)=0.5`.

The formula we will use to find the next three terms is:

nth term =
`a_1 * r^((n-1))`

5th term =
`16 * 0.5^((5-1)) = 1`

6th term =
`16 * 0.5^((6-1))` =
`(1)/(2)`

7th term =
`16 * 0.5^((7-1))` =
`(1)/(4)`
