Hi,
I have the formula to calculate the sum and average of the last 2 values in Column A if there are no gaps in the data. This works if I add further values into the column.
Formula under 'Sum': =SUM(OFFSET(A1,COUNT(A1:A17)-2,0,2))
Formula under 'Average': =AVERAGE(OFFSET(A1,COUNT(A1:A17)-2,0,2))
| 1.00 | Sum | Average | |||
|---|---|---|---|---|---|
| 2.00 | Last 2 values | 9.00 | 4.50 | ||
| 3.00 | |||||
| 4.00 | |||||
| 5.00 | |||||
However, when there are gaps in the data, the above formulae do not work in calculating the sum/average of the last 2 values in the Column:
| 1.00 | Sum | Average | |||
|---|---|---|---|---|---|
| 2.00 | Last 2 values | 5.00 | 5.00 | ||
| 3.00 | |||||
| 4.00 | |||||
| 5.00 | |||||
| 7.00 | |||||
As you can see, the sum should be 5+7=12 and the average should be of 5 and 7 (6),
Is there a formula I can use which would automatically discount blank cells?
Thank you!

If you have Microsoft 365 or use Excel Online:
=AVERAGE(TAKE(FILTER(A1:A17, A1:A17<>""),-2))
Hi,
In cell E2, enter this formula and drag down
=SUM(TAKE(TOCOL(A1:A7,1),-2))
In cell F2, enter this formula and drag down
=AVERAGE(TAKE(TOCOL(A1:A7,1),-2))
Hope this helps.
Thank you so much!
If you are using M365.
=SUM(A:A)-SUM(TAKE(FILTER(A:A,A:A<>""),COUNT(A:A)-2))
Or
=INDEX(FILTER(A:A,A:A<>""),COUNT(A:A))+INDEX(FILTER(A:A,A:A<>""),COUNT(A:A)-1)
For average, you may directly divide 2 from the sum value.
