The answer is 2.46
Hope it helps!
I will put an equation to the corresponding number.
1) Seven more than 2 times a number is 23 => 2n + 7 = 23
2) The difference of 2 times a number and 7 is 23 => 2n - 7 = 23
3) The sum of 7 times a number and 2 is 23 => 7n + 2 = 23
4) Seven less than 2 times a number is 23 => 2n - 7 = 23
Based on the choices. The equation that matches sentences 2 & 4 is letter b. 2n - 7 = 23
Though both sentences are structured differently and used different terms, they both refer to subtraction of 7 from the product of 2 and n to get the difference of 23.
Answer: Option a.
Step-by-step explanation:
1. The sequence shown in the problem is a Geometric sequence, because it has a common ratio. This means that when you multiply one of those numbers by the common ratio, you obtain the next number.
2. Then, you can calculate the common ratio as following:
![r=\frac{108}{-324}=-\frac{1}{3}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B108%7D%7B-324%7D%3D-%5Cfrac%7B1%7D%7B3%7D)
3. Therefor, the next term is:
![(12)(-\frac{1}{3})=-4](https://tex.z-dn.net/?f=%2812%29%28-%5Cfrac%7B1%7D%7B3%7D%29%3D-4)
the answer is
-10 times- 5
