The answer is the same answer 256
Try this option:
rule: common equation for a parabola is y=ax²+bx+c. If to re-write this equation in the form y=(x+m)²+n, then point (-m;n) is vertex of this parabola.
According to the described rule vertex is (7;9).
The graph of this function is in the attachment.
To express the sequence as recursion formula, we would do:
t₁ = 4 tn = 2(tn-1) +3
If you try to find the next number using this formula, you will get the right answer.

Answer:
(B) a negative correlation.
Step-by-step explanation:
If students who finish exams early tend to get better grades than students who hold on to exams until the last possible moment implies that if we collect data about time to finish an exam and the associated grade, then, for instance, for two diffent times the corresponding grades and will satisty with high probability.
