Question

The Monthly indexes for the first 11 months are: 1.25, 1.25, 1, 1, .75, .75, .7, .8, .8, 0.64,0.98. What is the index for the last month?

Answer 1

To find the index for the last month, we can use the average of the first 11 months and consider a desired average or pattern if any. However, you've not provided any specific requirement for the 12th month, so we'll find the average of the first 11 months.

Here are the provided monthly indexes:
1.25, 1.25, 1, 1, 0.75, 0.75, 0.7, 0.8, 0.8, 0.64, 0.98.

Now, let's calculate the average of these indexes:

1.25 + 1.25 + 1 + 1 + 0.75 + 0.75 + 0.7 + 0.8 + 0.8 + 0.64 + 0.98 = 10.0

Now, count the months (which is 11).

The average is:
Average = Total Sum / Count of months = 10.0 / 11 ≈ 0.909.

If we consider an average of around 0.909 for the 12-month period, we might guess that the 12th index can align itself with this.

However, without additional guidance on what specific approach to take or a desired outcome for the last month, I cannot definitively say what the index for the last month should be. More context on your goal would help to provide a more precise answer! If you have a specific target or trend in mind, please share so I can help further.
