Step-by-step explanation:
Answer:
Choice A:


Step-by-step explanation:

means we looking for first term 5 and the sequence is going up by 2.
In general,

means you have first term
and the sequence has a common difference of d.
So it is between the first two choices.
The explicit form of an arithmetic sequence is: 
An equivalent recursive form is 
So d again here is 2.
So choice a is correct.
