QBasic - How to find this value?

If we have M as follows:

M = 1+2+3+5+6+7+9+10+11+13+...+n

What would be the QBasic program to find M.

I have done the following so far, but is not returning me the expected value

INPUT "ENTER A VALUE FOR N"
SUM = 0
FOR I = 1 TO N
IF I MOD 4 = 0
SUM = SUM + I
NECT I

How should I go about this?

Thanks.

Solution

  • You have mixed the equality operator. Try this:

    INPUT "ENTER A VALUE FOR N"
SUM = 0
FOR I = 1 TO N
IF I MOD 4 <> 0
    SUM = SUM + I
NEXT I
