Answer:

<h2>(-6)×3ⁿ⁻¹</h2>

Step-by-step explanation:

We notice that in this sequence (an) we multiply by 3 each time to get the next term

e.g :  (-6)×3 = -18

then

the commonn ratio q = 3

Matthew bought 12 roses for his mother. Exactly 1 of the roses were white. How many of the roses were white?
insens350 [35]
<h3>hello!</h3>

What is \sf{\displaystyle\frac{1}{4}} of 12?

In order to find it, we should divide 12 by 4:-

3

Now, solve our word problem:-

Matthew bought 12 roses. \sf{\displaystyle\frac{1}{4} } of these roses were white.

And we already know how to solve this problem :)

Hence,

\bigstar{\boxed{\pmb{3~of~the~roses~were~white}}}

<h3>note:-</h3>

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
