Euler Problem 2

problem;

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:

1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

Find the sum of all the even-valued terms in the sequence which do not exceed four million.

my solution;

Sub Euler2()
   Dim first, second, temp, sum, limit
   first = 1
   second = 1
   sum = 0
   limit = 4000000   
   Do While second < limit
      If second Mod 2 = 0 Then
         sum = sum + second
      End If
              'ActiveCell.Value = second
              'ActiveCell.Offset(1, 0).Activate
      temp = first + second
      first = second
      second = temp
   Loop   
   MsgBox (sum)   
End Sub
