Find the next three terms.

243, -81, 27, -

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

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
