Stepwise summing from adjacent cell - excel

Summing down the way in excel. Im trying to calculate the total along a path in stepwise pieces, for example for each blank row I want the total from the left cell and add it to the total overall.
column 14 row 1 should be 3925.923, C14 R2 3925.923+1407.438, C14 R3 3925.923+1407.438 +1075.749 etc all the way to the bottom.

Use SUM() formula like-
=SUM($A$1:$A1)

Excel formula and drag down

I need to calculate Stand BA (highlighted on the right). This average is obtained by taking the sum of each plot's BA/ac value and dividing by the number of plots (for this example, there are 11 #1024 plots). The number of plots is always different. What formula could I use to apply the StandBA column so that I can drag it all the way down by plot number?
Try using =AVERAGEIF(A:A,A2,T:T).
It will return the average value from column T, and rows having the value of A2 (then A3, A4...) in column A will be the only ones to be taken into consideration for the calculation of the average value.
EDIT:
Use =IF(A2=A3,"",AVERAGEIF(A:A,A2,T:T)) if you want only the last rows of your Plot Id to contain the average formula (as shown on the screenshot in column U).
Example with columns A:C, formula pasted into C2 and dragged down to the last row.

Find cell by your position on cells total in a 2D array

I need find determined cell position based in yout position of range cells total.
Example:
In this table, i have 15 cells,"x" is 8th in these 15 cells and your position is B3. I need find B3 knowing only "x" is 8th cell in this range using a formula.
How to make a formula to find cell this way?
Assuming a 3 column wide area:
=ADDRESS(INT((F1-1)/3)+1,MOD(F1-1,3)+1)
Where F1 has the 8 and the 3s represent the number of columns in the area.

Excel function for averaging over an increment

I have a large table in excel with Column A running from 0 to 120 with increments of ~0.08 (This puts the last cell at 1441). I need to condense the table into increments of just 1. I need a function that can average the values from 0-1 and then be able to drag that function down so that the next cell references the next ~12 cells after the first. For Example: I need to average values from A1:A12, then when I drag the formula down 1 cell, it averages A13:A25, and so one.
Sample Data
=AVERAGE(OFFSET($A$1,12*(ROW()-1),0,12,1))
ADDED IN RESPONSE TO SAMPLE DATA
In cell H2 to get averages of column B you can use the formula
=AVERAGE(OFFSET($B$1,12*(ROW()-2)+1,0,12,1))
In cell I2 to get averages of column C you can use the formula
=AVERAGE(OFFSET($C$1,12*(ROW()-2)+1,0,12,1))
And so forth.

Adding all the values below the current cell in Excel

I am trying to display the total sum of all the numbers for a particular column. I want the sum to be displayed above the column as follows:
21 30
A B
6 5
6 10
6 10
3 5
I know I can sum the values and display it at the bottom of the column using =SUM(A3:INDIRECT("D"&ROW()-2)), however I am not getting a way to display it at the top of the column.
Please guide.
Based on the comments and the previous answers I suggest following formula, entered in cell A1:
=SUM(OFFSET(A$2,0,0,ROWS(b:b)-1))
You can then copy/paste to the right till second last column.
You could also modify your formula in A1 like this to achieve the same:
=SUM(INDIRECT("A2:A"&ROWS(A:A)-2))
But then you cannot copy/paste to the right...
A more general approach with your idea would be:
=SUM(INDIRECT(ADDRESS(ROW()+1,COLUMN())&":"&ADDRESS(ROWS(A:A),COLUMN())))
You can then copy/paste to the right till last column.
Some explanations:
Both formula sums up every value in the range from A2 till the bottom of column A (i.e. for Excel 2010 this would be A2:A1048576)
It doesn't matter if there are blanks or cells without value; the formula sums up only the numbers
I put A$2 and B:B in the OFFSET formula to avoid circular references, since I'm writing in cell A1 and I cannot write A$1 nor A:A
With the INDIRECT formula you don't have to worry about circular references
Further commenting (sorry, I don't have the credits to comment at the right place under the question):
Phylogenesis formula =SUM(A3:A65535) could also do the work, isn't it?
Didn't understand your question at first, because you talk of "sum of all the numbers for a particular row" but then you sum columns, isn't it?
When I'm doing something like this, I prefer to not include any empty cells beneath the range I'm summing, because I've had errors in the past as the result of including them (usually because there's a cell way down in the column somewhere that I'm not expecting to have a value). I'm assuming that A & B are your column headers. Assuming that, here is how I would do it. This is your formula for cell A1:
=SUM(OFFSET(A$1,2,0,COUNTA(A$3:A$65535)))
Explanation
I'm updating this with a brief explanation, per the OP's request.
According to ExcelFunctions.net:
The Excel Offset function returns range of cells that is a specified number of rows and columns from an initial supplied range.
The function reference for OFFSET is:
=OFFSET(reference, rows, cols, [height], [width])
What this formula does is create a dynamic range based on the number of cells in the selection, relative to cell A$1. This is an offset of two rows and no columns, which starts the range at A$3. The height of the range is the total number of filled cells in the range A$3:A$65535. The assumption here is that there are no blank cells in the range, which there were not in the sample data.

Want to auto fill across columns in Excel so that column number skips 2 each time

I want to be able to auto fill cells such that cell L3 contains the formula =T3-U3, cell M3, =V3-W3, cell N3, =X3-Y3, cell O3 =Z3-AA3, etc.
I've spent hours looking through every offset and indirect tutorial going and I just can't figure it out.
The closest I've got (for L3, say) is
=offset(R3,,COLUMN()+2,1,1)-offset(S3,,COLUMN()+2,1,1)
I think I want to use COLUMN()*2 somehow but, firstly, I don't understand the point of the reference cell if we're using 'COLUMN()', and secondly, I don't really understand what quantity is being multiplied by 2.
Please try:
=OFFSET($T3,,2*(COLUMN()-11)-2)-OFFSET($T3,,2*(COLUMN()-11)-1)
This anchors the reference point as the T column and adds an offset of -11 for a formula to be entered in the twelfth column (ie L).
COLUMN() is the reference number for the location (A=1, B=2, etc) and in Column L that is 12. We are interested in skipping to the column after the next (+2), so we take the offset (11) off of the column number we are in (12), then double that.
