Answer:
272 (D)
Step-by-step explanation:
First, find the relations between the 3 numbers. Tee population goes decreasing by 51 rabbits. Now, they are asking for the population during the first month. So now you have to go backward. The months are going by 3 so If you add one more column, it would go back to the first month, which is what we need. So you have to add 51 since you are going backwards instead of decreasing. 221 plus 51 is 272 which is your answer.
Hope this helps :)
