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.
