      Let’s say your sequence begins in cell A2.
      In cell A2, enter a 1
      In cell A3, enter this formula:
      Use the fill handle to drag that down as far as needed.

  • ratanak says:

    I often use COUNTA(A$1:A1) to add serial number.for filering i’d love SUBTOTAL(3,B$1:B1)

    • Puneet Gogia says:

      Thanks for sharing.

  • Derek says:

    The other day I learned the following:
    – in Cell A1 type the number 1
    – while holding down CTRL button, use Fill Handle on bottom right hand corner of cell A1 and drag down
    – you will see the numbers filled in sequential order as you drag down

    • Puneet Gogia says:

      Wow, MMA,

      Thanks for sharing.

      • Torstein S Johnsen says:

        Do I miss something here? I have put the subtotal function in A1 and copied it down. What I get is 0 (zero) in all my cells. I use the norwegian version and the 3 points to COUNTA, is that correct?

        • Puneet Gogia says:

          formula should be =SUBTOTAL(3,B$1:B1)
