The 11th term is 2, 095, 152

Explanation:
This is a geometric sequence, since each term after the first is obtained by multiplying a common ratio,
r
.
The common ratio is
4
. The first term,
a
, is
2
. The number of terms,
n
is
11
.
We use the formula
t
n
=
a
×
r
n
−

to determine the nth term in a geometric sequence.

Find -2/3 divided by 4/6<br> -1<br> 4/9<br> -9/4<br> 1

nalin [4]

Answer:

-1

Step-by-step explanation:

The given expression is:

$-\frac{2}{3}\div \frac{4}{6}$

We multiply by the reciprocal to get:

$-\frac{2}{3}\times \frac{6}{4}$

We factor so that we can cancel easily:

$-\frac{2}{3}\times \frac{3\times 2}{2\times 2}$

Cancel the common factors to get:

$-\frac{1}1}\times \frac{1\times 2}{1\times 2}$

This simplifies to:

$-1$
