I think 6 1/2,but I could be wrong so take that with a grain of salt
Answer:
6
Step-by-step explanation:
(8:100) * 75
(8*75) : 100
600:100 = 6
For the<span> geometric sequence, it has two forms of formula
</span>
<span>We are interested in the recursive formula now
</span>
<span>
{-80, 20, -5, ...}
The common ratio is (20/-80)=(-5/20)=-1/4=-0.25
So our r</span><span>ecursive formula would be
![a_n=a_{n-1}*(-0.25)=a_{n-1}*(- \frac{1}{4} )](https://tex.z-dn.net/?f=a_n%3Da_%7Bn-1%7D%2A%28-0.25%29%3Da_%7Bn-1%7D%2A%28-%20%5Cfrac%7B1%7D%7B4%7D%20%29)
</span>
I hope that
helps!
R-7=7 add the seven from both sides, leaving the r alone, because this is what you are trying to find. Thus the answer is r=14.
Answer: a because it’s using the commutative property of addition meaning it’s the same mathematical statement, it’s just moved around
