How do you graph it on a line

Aleonysh [2.5K]

In order to draw x ≤ -10 on a number line, first draw a closed dot at -10. This is because we have a ≤ and not a <. If we had a <, it would be an open dot.

Next, since we want x to be smaller, draw an arrow pointing towards all numbers that are smaller. This arrow would point to the left.

What is the seventh term of the geometric sequence with a first term of 729 and a common ratio of ?

SVEN [57.7K]

<u>Given</u>:

Given that the first term of the geometric sequence is 729.

The common ratio is $\frac{1}{3}$

We need to determine the seventh term of the sequence.

<u>Seventh term</u>:

The seventh term of the sequence can be determined using the formula,

$a_n=a_1(r)^{n-1}$

To find the seventh term, let us substitute n = 7 in the above formula, we get;

$a_7=a_1(r)^{6}$

Now, substituting $a_1= 729$ and $r=\frac{1}{3}$ , we get;

$a_7=729(\frac{1}{3})^{6}$

$a_7=729(\frac{1}{729})$

$a_7=1$

Thus, the seventh term of the geometric sequence is 1.
