Question

Let me know the answer plz

Answer 1

Answer:

The correct answer option is B. $1$, $\frac{1}{2}$, $\frac{1}{4}$.

Step-by-step 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 $(r) = \frac{2}{4}=0.5$.

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

nth term = $a_1 \times r^{(n-1)}$  

5th term = $16 \times 0.5^{(5-1)} = 1$

6th term = $16 \times 0.5^{(6-1)}$ = $\frac{1}{2}$

7th term = $16 \times 0.5^{(7-1)}$ = $\frac{1}{4}$
