Answer:
-6d^2+12d-3
Step-by-step explanation:
(15 +6d - d^2) + (-5d^2-18 + 6d)
=-5d^2-d^2+6d+6d+15-18
=-6d^2+12d-3
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.
