What is the formula for the nth term of 2 0 -2 -4 -6?

nth term = 2(2-n)

Since each number is 2 less than the previous number, the formula that comes to mind immediately is -2n. However, since the first number is 2 instead of -2, an additional adjustment is required. This can be done by adding 4 to each term. The result is:4-2n

equivalent to:

2(2-n)
