Pretty sure it’s c cause 5 x 20 = 100
Answer:
a. Arithmetic
b. 
c. 
Step-by-step explanation:
A sequence is arithmetic when the difference between one term and the next is a constant. On the other hand, a sequence is geometric when the next term is found by multiplying the previous by a constant.
In this case, the next term of the sequence can be found by adding $15. Therefore, the sequence is <em>ARITHMETIC ✔️</em>
The recursive formula will be the following: 
The explicit formula is the following: 
(0,-2) (3,2)
m = -2-2 / 0-3 → m = -4/-3 → m = 4/3
y = 4/3x - 2
To check if your answer is correct, choose any of the two coordinates. Plug the x and y in the equation. For example, use (3,2).
2 = 4/3 (3) -2 → 2= 12/3 -2 → 2 = 4 - 2 → 2 = 2. So if you get an answer like this, it means it's correct.
1. 2(10)
4(20)
6(30)
I only know the answer to number 1 sorry. :/
