# The nth term in the sequence is 2n - 6?

Hey Oscar, it looks like you've already answered the question! Usually we would work backwards to find out the nth term from a sequence of numbers. In this case it looks like we would have had a sequence like: -4, -2, 0, 2, 4 etc. where this sequence starts from the 1st term Detecting the difference between each number in the sequence and seeing that it 'goes up' by 2 each time, usually means the n is multiplied by 2, i.e. 2n We can only assume the '-6' part of the equation if we were told that the 1st term is -4. If we are not told which nth the original sequence is, you may be being asked a different question, like to determine which term a number would be (what is the value of n) based on the number in the sequence and the given equation. Hope this helps!
