Here's one way:
Flatten[Table[Take[Range[0,9],{i}],{i,2,9,3}]]
Best,

Subject: [mg114238] [mg114213] How do I take every 3rd number from a text file?
Hi,
I've been reading in text files using the following command:
ReadList["file.txt", Word]
However, now I only want to read in every 3rd number, starting with
the valueI specify.
For example, say I had these values:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9
How would I read in every third number, starting with the second
integer? So the result would look like this:
1, 4, 7
