ohhhhhh ok so let me try a problem
1 2 3 4 5
.............................................
6 12 18 24 30
so would it be 6n-12 ???
ok so you just say n2 when you are squaring? and im still not sure about the first problem because i dont get how you got f(n)=5??
well isn't it increasing by 1 every time?
ok what about this problem??
1 2 3 4 5 6
....................................
1 4 9 16 25 36
ok that makes sense but why do you need to find 0?? is that for every problem you do??
wait so how did you get 5-3n?
wait so did you get 4 becasue 4-3=1? and how would you take that formula and find the 20th term?
does anyone know how to write out the nth term? here is my problem...
1 2 3 4 5 6 n 20
.............................................
2 -1 -4 -7 -10 -13 ? ?
so how would you write out the nth term and find the 20th? please help!:D
