Answer:

The next two terms after a1 is

-6 and then 18

Step-by-step explanation:

Geometric sequence means your pattern for the terms is multiplication by the same number.

So a1 is the first term and r is your common ratio.

The common ratio is what you are multiplying by each time to figure out the next term.

So the geometric sequence goes like this:

a1 , a1*r , (a1*r)*r or a1*r^2 , a1*r^3 ,....

So anyways you have

first term a1=2

second term a2=2(-3)=-6

third term a3=-6(-3)=18

And so on...

Answer:

Step-by-step explanation:

Given:

Brett orders 2 meatball,1 turkey,1 veggie party-size sandwiches.

Each sandwich costs the same amount.

The total amount cost of the sandwiches, including tax, is $54.36.

Question asked:

What is the cost of each sandwich including tax?

Solution:

Let cost of each sandwich including tax = $x$

Total number of sandwich = 2 + 1+ 1 = 4

As each sandwich costs the same amount and total amount of cost of 4 sandwiches, including tax, is $54.36, the equation will be:-

$x+x+x+x=\$54.36\\4x=\$54.36$

By dividing both sides by 4,

$x=\$13.59$

Thus, the cost of each sandwich including tax is $13.59
