    1. The problem statement, all variables and given/known data

    Build a notation for the set: ##\{ ... , -8 , -3 , 2 , 7 , 12 , 17 ,...\}##

    2. Relevant equations

    ##2+5(0) = 2##
    ##2+5(1) = 7##
    ##2+5(-1) = -3##

    etc...

    3. The attempt at a solution

    ##\{ \ 2+5y \ | \ y \in \mathbb{Z} \ \}##

    Take note that you could replace ##2## by any elements of the set and it would still work.

    any thoughts appreciated!

    thank you!

    No , just wanted to be sure it was correct.I'm slowly getting better at those.

    Is that forbidden in this section? If so , I was unaware of it.

    thank you!

    No, it's OK to get confirmation that you're on the right track.
