Multiples plus X?

If I see a pattern that tells me it’s a multiple of 6 plus 1 do I CO in multiples of 7 or is the “1” only done once? I’ve been looking patterns for squares and a lot of them are done this way. When looking at the included chart I can’t figure out where the heck the “1” is! :??

The “1” is only counted the once so, for multiples of 6 + 1 you could start off with 7 or 25 or 61 etc.

Okay, got it! Thank you!
