Sum every odd row in a single Column VBA - excel

Question

I have a code that searches an excel fill for the word distance, takes the value of the cell next to it, paste it into a new cell, then sums all the cells up. Which works great, but i now need to find a way to only sum ever even row number. Does that make sense?
Sub Distance_Check()
Dim DistanceCheck As String
Dim DistanceNumber As String
Dim DistanceSum As String
Dim DistanceTotal As String
DistanceCheck = MsgBox("Would you like to check the distance?", vbYesNo)
If DistanceCheck = vbYes Then
If IsArray(fname) Then Workbooks.OpenText fname(1)
i = 1
findStr = "Distance"
Set foundCel = Range("A:A").Find(what:=findStr)
If Not foundCel Is Nothing Then
firstAddress = foundCel.Address
Do
Range("J" & i).Value = foundCel.Offset(0, 1).Value
Set foundCel = Range("A:A").FindNext(foundCel)
i = i + 1
Loop While Not foundCel Is Nothing And foundCel.Address <> firstAddress
End If
Set wkbSourceBook = ActiveWorkbook
DistanceNumber = i - 2
DistanceSum = WorksheetFunction.Sum(Range(Cells(2, 15), (Cells(DistanceNumber + 1, 15))))
DistanceTotal = DistanceSum / DistanceNumber
If DistanceNumber = Cells(2, 12) Then
MsgBox ("No error found wihin distance")
Else
MsgBox ("Error found with distance")
End If
Else
End If
Call Save_Data
End Sub
Would the way youd go about this be using a for loop on the
cells(DistanceNumber(j,+1)
Where j = 0,
j = j +2 ,
Until j > DistanceNumber,
Would that work? If so how would you go about it?
Thanks

A quick way to step through a loop in the desired increments is to use the Mod operator which divides two numbers and returns any remainder (e.g. 7 mod 2 = 1, as two sixes fit into seven, leaving one).
You can use the row property of the range you identify with the Find method, and since you want to jump by two the modulo should be zero:
If foundcel.Row Mod 2 = 0 Then Range("J" & i).value = foundcel.Offset(0, 1).Value
That said, there is a 'built in' way to step through a loop if using a For loop like this
For x = 2 to 10 Step 2
' Do stuff
Next x
You can also use this method to step backwards, e.g.
For x = 100 to 0 Step -10
' Do stuff backwards!
Next x
