I do have another question or need another formula, I would like to remove the mutiples of 7.

from what I can remember this may have something to do with geometric or was it arithmatic sequences.

so the first multiples would be 203, 210, 217

and the difference between them is obviously 7,

so now I need to find the sum of the multiples of 7 between 2 numbers, so I can subtract it from my total of 25250
