Esta macro deve fazer isso:
Option Explicit
Sub FillSequence()
Dim SrcSheet As Worksheet
Set SrcSheet = Sheets("Sheet1")
Dim SrcCol As Long
Dim SrcRow As Long
SrcCol = 10
SrcRow = 1
While Not IsEmpty(SrcSheet.Cells(SrcRow, SrcCol))
Dim StartNumber As Long
Dim EndNumber As Long
StartNumber = SrcSheet.Cells(SrcRow, SrcCol)
EndNumber = SrcSheet.Cells(SrcRow, SrcCol + 1)
If EndNumber < StartNumber Then
MsgBox "Input data wrong."
Exit Sub
End If
Dim Number As Long
For Number = StartNumber To EndNumber
ActiveCell = Number
ActiveCell.Offset(1, 0).Select ' This part could be optimized so
' that the selection does not have
' to be updated each time - but
' this should suffice for the
' moment. Just let me know if the
' performance is too bad for
' practical use.
Next
SrcRow = SrcRow + 1
Wend
End Sub
Ele assume que seus números estão na Planilha1 nas colunas J e K (ou 10 e 11) e começam na primeira linha. Basta executá-lo ao selecionar a primeira célula em que a sequência deve começar. HTH.
