Question

1,2,4,7,11 only the rule, and not in n's, i need it in y's and x's

Answer 1

stupid teacher... asking for the wrong notation lol

Answer 2

You know that all number ordering is in \[n\] right?

Answer 3

why is y and x special?

Answer 4

i cant figure out the rule here...

Answer 5

well, thats how my teacher wants it, lawl

Answer 6

tell her shes retarded

Answer 7

its a he, lol

Answer 8

lol i didnt see it at first either arman, myininaya got it though.

Answer 9

oh nevermind

Answer 10

how do you know minaya got it??

Answer 11

n=(2n) +1

Answer 12

that doesnt apply to the first term though

Answer 13

i don't think he wants my recursive pattern
i think he is rejecting it

Answer 14

nope

Answer 15

mines wrong.. :P

Answer 16

its a recursive pattern for sure, the rest of this guys questions were

Answer 17

the last time he posted the question Myininaya got it, but i guess the teacher doesnt want that type of notation.

Answer 18

i said
\[f_n=f_{n-1}+n, where f_1=2\]

Answer 19

maybe we could find a closed formula? one that isnt recursive?

Answer 20

for n>=2

Answer 21

thats not correct though, is it?

Answer 22

fn=fn-1+n, where f1=2 is that what that says?

Answer 23

oh damn it is, and its exatly what i was thinking too lol stupid fibancci

Answer 24

\[f_2=f_{2-1}+2=f_1+2=2+2=4\]
\[f_3=f_{3-1}+3=f_2+3=4+3=7\]

Answer 25

tell your teacher to shutup and accept this as an answer

Answer 26

i didnt know algebra homework was this complicated

Answer 27

\[f_4=f_{4-1}+4=f_3+4=7+4=11\]

Answer 28

it isint, ur teacher is just stupid...

Answer 29

ignorant, asinine, naive, insolent, retarded, foolish, incapable, under-sophisticated, under-qualified, etc

Answer 30

well the one I answered before the 2 4 6 8 16 one I got wrong canw e go back and work that one out

Answer 31

i looked again and its actually bad

Answer 32

the 2 4 6 8 16 one, is wrong?

Answer 33

yeah sorry.. it works for the first 4 terms but then goes haywire with the 5th

Answer 34

ugggh, why did i join honors algebra, i shouldve just done geometry, dumb summer homework

Answer 35

i think this will work as a closed formula:
the nth term is:
\[\frac{1}{2}(n(n-1))+1\]

Answer 36

how about:
\[y _{n} = y _{n-1}+x\]

Answer 37

its in xs and ys and its the same as the series formula

Answer 38

lol does x=n?

Answer 39

shutup...

Answer 40

technically ANYTHING could equal n :p
