Answer:

Seven.

Step-by-step explanation:

-3-(-8)-(-2)

Using PEMDAS, we are working with only subtraction, which means we will be moving from the left to the right.

Let's start with -3-(-8)

At first it seems like -3-8, which would be -11, HOWEVER, this is incorrect, because it is -8, not 8.

When subtracting a negative number, like we are doing in this problem, it actually turns into addition.

Therefore, -3-(-8) becomes -3+8, which is 5.

After doing this, we have 5-(-2).

Again, we are subtracting a negative number, so in actuality you want to add it.

So instead of 5-(-2), we are actually doing 5+2, which is 7.

Therefore -3-(-8)-(-2) is 7.

The first term of a geometric sequence is 32, and the 5th term of the sequence is 818 .

sammy [17]

Answer:

$32,24,18,\frac{27}{2} ,\frac{81}{8}$

Step-by-step explanation:

Let x, y , and z be the numbers.

Then the geometric sequence is $32,x,y,z,\frac{81}{8}$

Recall that term of a geometric sequence are generally in the form:

$a,ar,ar^2,ar^3,ar^4$

This implies that:

a=32 and $ar^4=\frac{81}{8}$

Substitute a=32 and solve for r.

$32r^3=\frac{81}{8}$

$r^4=\frac{81}{256}$

Take the fourth root to get:

$r=\sqrt[4]{\frac{81}{256} }$

$r=\frac{3}{4}$

Therefore $x=32*\frac{3}{4} =24$

$y=24*\frac{3}{4} =18$

$z=18*\frac{3}{4} =\frac{27}{2}$
