Answer:
I believe it is the second answer;
F(x)= (1/2)(2)^x
Step-by-step explanation:
1. the initial value is 0.5, so the first number will have to be 1/2, and it is increasing so the value of <em>b</em> must be above 1.
2. Through process of elimination, you can determine that the second equation matches the graph.
I hoped this helped! Please comment if you have any questions :)
Sarah is 14
The twins are 12
The youngest (n) is 7
14+(12+12)+7=45
n=7
Write a recursive rule for the sequence.
-2,0,2,4,6
STEP 1:
a1 = -2
a2 = 0
a3 = 2
STEP 2:
d = a2-(a1)=a3
= d = 0-(-2)=2
STEP 3:
An = a+(n-1)d
