Answer:
Option D is correct
Step-by-step explanation:
Option D is correct
Being an arithmetic sequence there will be common difference between the consecutive terms
Option A is incorrect because it is not necessary that explicit formula is an arithmetic sequence we can create explicit formula for any sequence
Option B is incorrect because recursive formula can be created for any sequence for geometric series also.
Option C is incorrect because the sequence that has constant ratio is the geometric sequence not an arithmetic sequence.

We have system:
y=2x+1
y=2x^2+1
To find which ordered pair is solution to this system we need to solve system for x and y.
Left sides are same so the right sides must be same too.
2x+1=2x^2+1
2x-2x^2+1-1=0
2x-2x^2=0
2x(1-x)=0
x1=0
x2=1
y1=2*0+1=1
y2=2*1+1=3
The solution are pairs (0,1) and (1,3).
