An = -2n + 4 ; where n is the sequence number or order.
a1 = -2(1) + 4
a1 = -2 + 4
a1 = 2
a2 = -2(2) + 4
a2 = -4 + 4
a2 = 0
a3 = -2(3) + 4
a3 = -6 + 4
a3 = -2
a4 = -2(4) + 4
a4 = -8 + 4
a4 = -4
So the first four terms of the sequence are: 2, 0, -2, -4
Answer:
The required form is
.
Step-by-step explanation:
Consider the provided quadratic function.

We need to put the equation into the form 
Add and subtract 49 in order to make the above function a perfect square.




Hence, the required form is
.
(x-8)²= x²-16x+64
x²-16x+8=0
Therefore 56 must be added.
Good luck
