Find the next 3 numbers in the sequences? ?

Question

1.) 3,-1,-3,-3,-1,3,9

2.) 0,1,8,27,64

3.)1,1,2,3,5

-Tell me how you did them as well.

Answer 1

1.) 17, 27, 39 (I forget what its called... Its not linear, not exponential... the other relationship)

2.) 125, 216, 343 (cubed numbers)

3.) 8, 13, 21 (add the last two numbers together)

Answer 2

The one who asked you doesn't know how ignorant she is.  

Answer 3

Snow Prince's answers look right.  If you want to annoy the c**p out of whoever asked you that, you can solve the third one a different way:

1,1,2,3,5

1(+0),1(+1),2(+1),3(+2),5(+2),7(+3),10...

There's at least 2 other ways I can think of to find a pattern in this one.  You can multiply instead of add, or you can count it as a 1, 2, 1 pattern instead of just a 2, 2, 2 kind of pattern.

Answer 4

1) 3,-1,-3,-3,-1,3,9,17,27,39

pattern : diff between numbers: -4,-2,0,2,4,6,8,10,12, etc

2) 0,1,8,27,64,125,216,343

pattern:

log (base of 1) 1 = 3

log (base of 2) 8 = 3

log (base of 3) 27 = 3, etc

3) A => 1,1,2,3,5,7,9,11

pattern A = prime number

3) B => 1,1,2,3,5,7,10,13

pattern B = diff between numbers: 0,1,1,2,2,3,3,etc
