Question

Let me know the answer plz

Answer 1

The correct answer option is A.
`(1)/(16)`.

Explanation:

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

`1024, 256,64,...`

Here
`a_1=1024` and common ratio
`(r) = (64)/(256) =0.25`.

The formula we will use to find the 8th term is:

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

Substituting the values in the formula to get:

8th term =
`1024 * 0.25^((8-1))`

8th term =
`\frac { 1 } { 1 6 }`
