The terms in the sequence decrease by the same amount each time: 9, 6 ,3 ,0, -3, -6
Work out ,in term of n, the nth term of the sequence

-3n+12

Step-by-step explanation:

The sequence is decreasing in value as it goes along, meaning that the nth term needs to be negative for it to work. It's decreasing by 3 so we write -3. We then add to -3 to get to 9. This means we add 12 to get to 9. So we put those 2  together and get -3n+12

maybe - definition of supplementary angles. im not sure. sorry
