We can figure this out using the explicit formula.

n represents the term we are looking for.f(1) represents the first term in the sequence, which in this case, is -242.d represents the common difference, which in this case, is -9.
f(n) = -242 + -9(n - 1)
f(n) = -242 - 9n + 9
f(n) = -233 - 9n
Now, we can input 28 for n and solve.
f(28) = -233 - 9(28)
f(28) = -233 - 252
f(28) = -485
The 28th term of the sequence is -485.
i would say B
when it says "the measure", it's refering to where the second quartile is beginning
Theoretical Probability is what you think the result will be, and experimental probability is what it turns out to be, hope this helps.
