Muliply .15 to 828 and get your answer the add it to 828
oops i just did :)
Point-slope form is y - y_1 = m (x - x_1) where x_1 and y_1 are the given coordinates and m is the slope. When you plug the given values into the equation you get y - 3 = 6 (x - 8) .
Assuming the sequence goes on like this 11,-33,99,-297,891,...,
its general formula is

So, the 9th term is
7. -20
10 3
6 3
Subtract each remember 4-- -6= 10
