16. It's basically the problem you started with, but just reversed.
Muitply by two on both sides then subtract then divide to find x
Sequence will look like this:
Term 1: 20 --------- 20 + 5(0)
Term 2: 25 --------- 20 + 5(1)
Term 3: 30 --------- 20 + 5(2)
Term 4: 35 --------- 25 + 5(3)
ETC.
It cab noted that the numbers in the bracket (that is, 0, 1, 2, 3, 3, etc) = n-1
Then, the explicit formula will be;
an = 20 + 5(n-1).
The correct answer is D.
A. Gloria because Gloria isn't being showed something shes the one showing something to someone else.
f' = -4x+8=0 => x=2
=> f(2) is the maximum = 11
