Write an equation that models the sequence 200, 500, 1250,

a) y = 120x + 80
b) y = 80(0.4)x
c) y = 80 (2.5)x
d) y = 80 (120)x

I don't know what it means by "models the sequence" yet, but here is an equation describing the sequence if it helps any: x2 + (x.5)

The first term is 80 and the common ratio is 2.5 because every term is being multiplied by 2.5.  to figure this out when it is not obvious, divide the 2nd term by the first term.  the equation is   y = 80(2.5)^x

where are the choices?

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
