Find the next three terms.<br><br> 243, -81, 27, -9...

Katarina [22]

Hi there!

To find the answer, you divide one of the numbers by 3, and some others by -3.

I can show you how to do so! :D

243 ÷ -3 = -81

-81 ÷ 3 = 27

27 ÷ 3 = 9

Next three terms -

9 ÷ 3 = 3

3 ÷ 3 = 1

1 ÷ 3 = 0.3333, the 3 is repeating over and over again

I think this is the answer, based off my notes :)

That's your pattern!

Hope this helps!

Message me if you need anything else, I'd be happy to answer any other questions! :D
