I don't see any choices so I am going to give you what I think the answer would be. The rule would be 3x. That would be you could plug any number in and they would give you the sequence. Example:
x = 1
x times 3 = 3.
We could even find future things like:
x = 10
x times 10 = 30.
If we were doing it based on the algebraic expression it would be "multiplication" because we are multiplying. Hope this helped. :)
40 x $6=$240
<span>6.5 x $9=$58.50 </span>
<span>8 x $ 12=$ 96 </span>
<span>Answer $394.50</span>
Assume widthis x-2
perimeter is 2*(width+length)
so 2*(x+x-1)>112
2*(2x-1)>112
4x-2>112
x>28.5
so any length greater than 28.5 will work
Your answer is the second option, -3, -6, -12, etc.
The information we are given tells us that a1 = -3 and an = 2 × a(n - 1). This means that if we want to find the value of a2, we just need to substitute -3 into the equation:
a2 = 2 × a1 = 2 × -3 = -6
And then to find a3, we substitute in a2, which in this case is -6, so:
a3 = 2 × a2 = 2 × -6 = -12
The only option with the first 3 terms as -3, -6, -12 is the second option, so that is the answer.
I hope this helps!
