*I know it's already been answered, but I just wanted to add a different version of the steps. While this particular question could be answered in like 3 seconds, this method is a lot quicker when they want you to find 30th term lol

Answer:

500

Step-by-step explanation:

First, set up your equation:

a<em>n </em>= a<em>1 </em>* r ^ (n-1)

a<em>1 </em>is 2000, because it is the first term (4000 is the 0th term).

4000*(1/2)=2000.

a<em>n </em>= 2000<em> </em>* (1/2) ^ (<em>n-</em>1)

Now, subsitute <em>n </em>for 3:

a3<em> </em>= 2000<em> </em>* (1/2) ^ (3-1)

Solve:

a3 = 2000 * (1/2) ^ 2

a3 = 2000 * 0.25

a3 = 500

28 ,81, 100, 121,<br><br><br> 7, 9, 10, 11,
Alexxx [7]

The length is 10 and the area is 100 because 6,8,10 is a pythagorean triple. 36 + 64 = 100 and the square root of 100 is 10. 10 ^ 2 is the area which is 100. If this is right could you possibly give me brainliest? Hope this helped.
