Answer:
The second option
Explanation:
Plug in one variable at a time
The first one
2(1)/1+1 should equal 2/2 or 1, but they have 2/3
Plug with other numbers and they don't work either
The second one
1 works, as shown previously
Now let's try 2
2(2)/2+1 should equal 4/3, which is what is stated
Keep on going with increments of 1 until you get to 5 and you'll see that all of them work
The third one
It just doesn't follow a patterned sequence with increments of the same number
Same situation for the fourth one
Therefore, the second option is the only one that works
