Answer:
24/49
Step-by-step explanation:
Let's add the terms and see if there's a pattern

Suppose we say the sum of n terms is (n/(2n+1)), the next term in the series will be 1/((2n+1)(2n+3)) and adding that to the presumed sum gives ...

Then it appears the sum of n terms is (n/(2n+1)). So, the sum of 24 terms is ...

It would be 1008 people because all you would do is 114 times 7 and that would be the answer. Why? Because you need to take the amount of people per train and multiply that by the amount of cars. Hope this helped comment if it did!
This is the concept of functions. We are required to calculate for the total cost of tickets if 27, 39 and 43 people attended a concert whose cost was represented by C=10n+26.
To solve for this we substitute the each values in the function as follows;
When n=27
C(27)=10*27+26=296
When n=39
C(39)=10*39+26=416
When n=43
C(43)=10*43+26
=456
The approximate area will be 128.63 ( or 128.625 ) feet squared
