What is the 9th term of the geometric sequence 4, −20, 100, …?
sveta [45]
First, we are going to find the common ratio of our geometric sequence using the formula: r= \frac{a_{n}}{a_{n-1}}. For our sequence, we can infer that a_{n}=-20 and a_{n-1}=4. So lets replace those values in our formula:
r= \frac{-20}{4}
r=-5

Now that we have the common ratio, lets find the  explicit formula of our sequence. To do that we are going to use the formula: a_{n}=a_{1}*r^{n-1}. We know that a_{1}=4; we also know for our previous calculation that r=-5. So lets replace those values in our formula:
a_{n}=4*(-5)^{n-1}

Finally, to find the 9th therm in our sequence, we just need to replace n with 9 in our explicit formula:
a_{9}=4*(-5)^{9-1}
a_{9}=4*(-5)^{8}
a_{9}=1562500

We can conclude that the 9th term in our geometric sequence is <span>1,562,500</span>

I'd seriously appreciate it if anyone could help ASAP! I'm giving Brainliest!
Elina [12.6K]

Answer:

- 16/5

Step-by-step explanation:

We have point with coordinates (-6, y) which lies ( or belong) on the graph of the straight line 5y=2x-4

When we replace x= -6 in given equation we get 5y = 2·(-6)-4 => 5y= -12-4 =>

5y= - 16 => y= - 16/5

Good luck!!!
