Answer:
Step-by-step explanation:
(cant remeber the exact word right now) think of it like this. if your school is going on a feildtip, there are 40 students in a group while there are 25 adults in a group. so the equation you are trying to find is
x:1 what you would do is divide 40 both numbers by the second number so you would divide 40 by 25 to get you 1.6
clearly it is not talking about people. but the answer is 1.6 : 1
Answer:
![a_n = -5 +(n-1)*2](https://tex.z-dn.net/?f=a_n%20%3D%20-5%20%2B%28n-1%29%2A2)
Step-by-step explanation:
<u>Step 1: Determine the variables</u>
Initial number is -5
Increments of +2
<u>Step 2: Create an explicit formula</u>
![a_n = initial+(n-1)*increment](https://tex.z-dn.net/?f=a_n%20%3D%20initial%2B%28n-1%29%2Aincrement)
![a_n = -5 +(n-1)*2](https://tex.z-dn.net/?f=a_n%20%3D%20-5%20%2B%28n-1%29%2A2)
Answer: ![a_n = -5 +(n-1)*2](https://tex.z-dn.net/?f=a_n%20%3D%20-5%20%2B%28n-1%29%2A2)
