8. precal Group Title

ok just a lot of guess and check but that one works

9. bmelyk Group Title

i know those formulas but, im not sure how im supposed to start it. like how do you know what n equals?

10. bmelyk Group Title

@precal

11. precal Group Title

you can use n or k

12. precal Group Title

I just notice that the numerators were 1,2,3,4,5,6,7

13. precal Group Title

so I knew I could use n or n+1

14. precal Group Title

the denominators were odd 1,3,5,7,9,11,13 in math we use 2n+1 for odd for evens we use 2n

15. precal Group Title

I had to guess whether to use n=0 or n=1 as my first numbers, so that is why you see me testing them|dw:1359577972172:dw|

16. precal Group Title

there really is no one way to do these, just a lot of guess and check

21. precal Group Title

22. bmelyk Group Title

23. precal Group Title
