Question

Let me know the answer plz

Answer 1

Answer:

The correct answer option is A. $\frac{1}{16}$.

Step-by-step 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 $(r) = \frac{64}{256} =0.25$.

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

nth term = $a_1 \times r^{(n-1)}$

Substituting the values in the formula to get:

8th term = $1024 \times 0.25^{(8-1)}$

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