The easiest way is to use the `OFFSET`

function. The function prototype appears as follows:

```
=OFFSET(range, rows, columns, height, width)
```

To apply this for your situation, set `range`

to the first cell of data (use an ABSOLUTE reference, see below in the formulas), `rows`

to the offset, `columns`

to 0 (since we don't want to shift the column), and finally set `height`

and `width`

to 1 (since we are returning a single cell).

So, assuming your data above is in column A, you can return the 4th, 8th, and 12th entry via the following formulas:

```
=OFFSET($A$1, 3, 0, 1, 1) or =OFFSET($A$1, 4 - 1, 0, 1, 1)
=OFFSET($A$1, 7, 0, 1, 1) or =OFFSET($A$1, 8 - 1, 0, 1, 1)
=OFFSET($A$1, 11, 0, 1, 1) or =OFFSET($A$1, 12 - 1, 0, 1, 1)
```

Note that you subtract 1 from each, since `rows`

is an OFFSET (so to get cell A4, you offset A1 by 3 rows, not 4). If you enter the first few cells manually, you can use Excel's auto-fill function to perform this automatically for the rest of the data.

You can also use the `INDIRECT`

formula to accomplish this. First, make a new column with the row numbers you want (e.g. 1, 5, 9...). Then, in the adjacent columns, put the formula `=INDIRECT("A" & REF)`

where `REF`

is the cell to the left (with the row number), and "A" is the column containing your data.

Obviously, you can do this for any arbitrary number set. So, if you enter the following into Excel:

```
A B C
1 D1 4 =INDIRECT("A" & B1)
2 D2 8 =INDIRECT("A" & B2)
3 D3 12 =INDIRECT("A" & B3)
4 D4
5 D5
6 D6
7 D7
8 D8
9 D9
10 D10
11 D11
12 D12
```

You will see the contents `D4`

, `D8`

, and `D12`

in column C. You can use auto-fill to extend these formulas as far as you need.
