Answer:
a n = -3+(n-1)-30
Step-by-step explanation:
-3 - 30 = -33
-33 - 30 = -63
-63 - 30 = -93
The common difference here is -30. d = -30
The explicit formula is a n = a1 + (n-1)d
Answer:
64.96
Step-by-step explanation:
The most common benchmark percents are and
We are given which is closest to .
Now we calculate which is equal to .
We are left with more to add.
