Explanation / Answer

Month Actual Value : Predicted Value Ratio

January 154400 198996 1.28

May 186359 182495.5 0.98

June 189244 183784 0.97

July 184978 187801 1.01

The predicted values are calculated by taking an average of the previous two months actual values.

As we can see,the ratio for January is the highest and most divergent from 1 than the others.

Hence,the answer is January
