How can I put A={1,4,7,10,13,16,19,22,25,28} in set builder notation. I just learned this and can't figure it out.

  • math -

    notice all the numbers are 3 apart

    so the formula to generate the numbers would be
    3n - 2, where n ∈ N0

    so

    A = { 3n-2 | n ∈ N0 , n ≤ 10 }

  • oops -math -

    I just noticed that I wanted the n's to start at 1, not at 0
    so change it to

    {......| n ∈ N ......}
