Use that r value and
to find the first term
![s_n = s_1*(r)^{n-1}\\\\s_4 = s_1*(2)^{4-1}\\\\18 = s_1*8\\\\s_1 = \frac{18}{8}\\\\s_1 = 2.25](https://tex.z-dn.net/?f=s_n%20%3D%20s_1%2A%28r%29%5E%7Bn-1%7D%5C%5C%5C%5Cs_4%20%3D%20s_1%2A%282%29%5E%7B4-1%7D%5C%5C%5C%5C18%20%3D%20s_1%2A8%5C%5C%5C%5Cs_1%20%3D%20%5Cfrac%7B18%7D%7B8%7D%5C%5C%5C%5Cs_1%20%3D%202.25)
You could use
in place of
(just make sure to use n = 6 instead of n = 4).
Answer:
A, the correct answer is A
A) divide 1.5 hrs by 3 to get .5 hr than divided 93mi by 3 to get 31 than add .5hr to another .5hr to get 1hr than add 31 to 31 to get 62 so the answer for A is (1hr=62mi)
B)Turn 1.5 hrs to minutes which is 90 than divide by 18 to get 5 minutes and do the same with the miles 93 divided by 18 equals the answer is (5minutes= <span>5.16666666667miles)</span>
I believe the answer is the third option.
1/2x is the slope and +3 is the Y-intercept which we already know is 3.
The graph is going up so its going to be a positive 3.
