We have the representation of this problem in the figure below. As we have a 10.3 mile race, then the equation is fulfilled as:

We know that there is <span>a water station that is twice as far from the starting line as from the finish line, then:
</span>

So:

∴

and

<span>Finally, the distance of the runner from the finish line is:
</span>
First four terms are 7, -13, 67, -253
<em><u>Solution:</u></em>
Given that,

<em><u>The formula to find nth term is given as:</u></em>

We can find the first four terms by substituting n = 2, 3, 4
<em><u>First term:</u></em>
f(1) = 7
<em><u>Second term:</u></em>
Substitute n = 2

<em><u>Third term:</u></em>
Substitute n = 3

<em><u>Fourth term:</u></em>
Substitute n = 4

Thus first four terms are 7, -13, 67, -253
Answer
39.81
Step-by-step explanation:
First I converted the percent to a decimal which was 0.15
Then I multiplied 0.15 by 34.62 which was 5.193
Lastly I added 5.193 by 34.62 which was 39.813
I rounded it to 39.81
