It's like if you say {1,2,3,4,5,6,7,8,9,10,11,12} This is that in set builder notation: {x|x= N < 13) And that says X such that x equals the natural numbers less than 13. Duckie

3. Looks simple, increasing by 2 more every time |
|
100, 121, 144, 169, etc.
The first number increased by 3, from 1 to 4. Every subsequent addition is 2 mored than the previous -- 5,7,9, etc.

5. Well, I've figured out that every time they add the next number... |
|
in the multiples of three. 1,4,9, etc... 1+3=4, 4+5=9, etc. I just don't know how to say that. Duckie
