Answer:
D) -2, -1, 2, 7, 14
Explanation:
Let's take the first five whole numbers.
0, 1, ,2, 3, 4
Now plug in n =1 in the explicit formula An = n^2 -2
When n = 0,
A0 = (0)^2 - 2 0 - 2= -2
When n = 1,
A1 = (1)^2 - 2 = 1 - 2 = -1
When n = 2,
A2 = (2)^2 - 2 = 4 - 2 = 2
When n = 3,
A3 = (3)^2 - 2 = 9 - 2 = 7
When n = 4,
A4 = (4)^2 - 2 = 16 - 2 = 14
Therefore, the first five terms are -2, -1, 2, 7, 14
Thank you.
