The sum of 6 consecutive even numbers is 126.what is the fourth number in this sequence

This can be put into a formula like so:

Since they are 6 consecutive even numbers, they will alternate odd/even/odd/even.

x, x+2, x+4, x+6, x+8, x+10 = 126

Simplify

6x + 30 = 126

6x = 96

x = 16

And you want the fourth number, so plug the x value back into the equation of 'x+6' and you will get 16+6 which = 22.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
