In a sequence of numbers, `a_{3}=0`, `a_{4}=6`, `a_{5}=12`, `a_{6}=18`, `a_{7}=24`. Based on this information, which equation can be used to find the `nth` term in the sequence `a_{n}`?
The common difference between each term is 6, since the difference between `a_{3} = 0` and `a_{4} = 6` is 6, and so on. Therefore, the equation to find the `nth` term in the sequence is:
`a_{n} = 6n - 18`
