if...8,14,48,100.....          then what would be a next term??
(a)180            (b)176

anonymous · Answer

Ok maybe this helps 

2x4 , 2x7,2x2x12,2x2x25,...

anonymous · Answer

im come to hate these questions now lol

anonymous · Answer

176 = 2x2x2x2x11
180 = 2x2x3x3x5

anonymous · Answer

well 176 suits more ...I am with 176

anonymous · Answer

i can come up with two equations <.< one that makes a work and then one that makes b work >.> they will look really really ugly though.

anonymous · Answer

please upload them ..it will definitely help

anonymous · Answer

they wont be the "correct" answer though.  i havent made them yet btw, i know how though.

anonymous · Answer

its more of a "take this for not giving us enough terms to see the pattern" in your face thing lol

anonymous · Answer

lol

jhonyy9 · Answer

nice i am with 176 too

anonymous · Answer

Someone give me 5 numbers between -10 and 10

anonymous · Answer

-9 ,-3,0,2,3

myininaya · Answer

i was thinking 176 too just because 180 is too pretty

anonymous · Answer

hmm, switch the 0 for something else <.< i dont think i can make that work

anonymous · Answer

lol

myininaya · Answer

1

anonymous · Answer

lol 180 is pretty 
$$\large{180}$$

jhonyy9 · Answer

because 8+6=14 and 6*8=48

anonymous · Answer

k, one sec

anonymous · Answer

but how will you approach 100 with that jhonny

myininaya · Answer

wait!

jhonyy9 · Answer

8+14+48+100=170+6=176

myininaya · Answer

wait nvm

anonymous · Answer

ok see this 

$$3^2 -1 = 8$$
$$4^2 - 2= 14$$
$$7^2 -1 = 48$$
$$10^2- 0 = 100$$

anonymous · Answer

the 100 makes it look  bad

anonymous · Answer

ok maybe 

$$13^2 + 7= 169  +7 = 176$$
value goes from 0 to +ve lol it sounds very bad

anonymous · Answer

$$\frac{37}{11880}(-9)^n-\frac{119}{360}(-3)^n-\frac{1}{40}(1)^n+\frac{122}{55}(2)^n+\frac{7}{8}(3)^n$$

Plugging in n = 1, 2,...., 5  gives 8, 14, 48, 100, 180.

myininaya · Answer

lol

anonymous · Answer

http://www.wolframalpha.com/input/?i=%2837%2F11880%29%28%E2%88%929%29^n%E2%88%92%28119%2F360%29%28%E2%88%923%29^n%E2%88%92%281%2F40%29%2B%28122%2F55%29%282%29^n%2B%287%2F8%29%283%29^n%2C+n+%3D+5 Just switch the n = 1 to another number to see the value.

anonymous · Answer

keep in mind this isnt the correct answer though >.> just a trick.

myininaya · Answer

why can i never see a pattern anymore :(

anonymous · Answer

i know =/ i thought i was decent at spotting relationships =/

anonymous · Answer

But your relation joe it looks ....how did you derived it

anonymous · Answer

you pick as many random numbers as you need.  since i wanted the value of the function to match 5 numbers i picked 5.   Then you set up something like:
$$c_1(r_1)^n+c_2(r_2)^n+c_3(r_3)^n+c_4(r_4)^n+c_5(r_5)^n$$
each r is one of the numbers you picked.  So your goal is to figure out what the constants are.

anonymous · Answer

i just create a matrix that will give me the coefficients. usually they are really ugly.  But as you can see, one could create infinitely many formulas by picking different numbers.

anonymous · Answer

yeah but good one

anonymous · Answer

its what the teacher gets! giving us some sequence with no observable pattern >.>

anonymous · Answer

How can they prove my answer is wrong? they cant! i win >.>

anonymous · Answer

seriously your school is so good ... i like this thing make patterns

myininaya · Answer

joe is awesome
i wish had his super powers

anonymous · Answer

lol, im just covering for the fact i dont know the answer to this problem :P

anonymous · Answer

Lets vote ...make wrong right(if we vote wrong more )


I am with 176

anonymous · Answer

i say 176 as well.

anonymous · Answer

ok 

176   |   180 
         |
  2     |     0

myininaya · Answer

well i think 180 now

jhonyy9 · Answer

176 too

myininaya · Answer

we couldn't find a pattern that made 176 work
he can show the pattern joe found to support is answer as 180
he has no evidence for this 176

anonymous · Answer

i would like to switch my vote.

myininaya · Answer

lol

anonymous · Answer

176 | 180
   2      2

myininaya · Answer

so now we can make it 50 50
so he won't be able to say he got a wrong answer from open study

anonymous · Answer

jhonny lets switch these guys are not wrong

anonymous · Answer

do we battle to the death now?

myininaya · Answer

we could be wrong lol who knows

myininaya · Answer

ishaan dont give into peer pressure

anonymous · Answer

watch the teacher come back with some linear formula >.> i'd be mad!

myininaya · Answer

this doesn't look linear

anonymous · Answer

yeah its not, good point.

myininaya · Answer

i wonder if this person is in algebra or some class close to the ground of math

anonymous · Answer

look at this

anonymous · Answer

differences 
14-8 = 6
48- 14= 34
100-48=52 

6,34,52

anonymous · Answer

2x3 , 17 x2 , 13x2x2

anonymous · Answer

176 - 100 = 76

19x2x2 = 76

anonymous · Answer

all prime good primes 
17 , 13 ,19

anonymous · Answer

thats is not with 80

anonymous · Answer

180 -100 = 80 not possible

anonymous · Answer

it's just random

jhonyy9 · Answer

if begin with 6,8,14,48, ... ??? can we get 100 ?

myininaya · Answer

i give up

myininaya · Answer

i am walking away and not looking back

anonymous · Answer

me too, i just dont see anything =/

myininaya · Answer

if i don't this problem will drive me crazy

anonymous · Answer

me too ;  i advise this to everyone who reads  this question
