Question

What are the next three terms of the sequence :
-30, -14,-6,-2,0?

Answer 1

it looks like you increase by an amount to get to the next term... but the amount you increase changes with each term. Can you see the pattern?

Answer 2

no, I dont see it, can you explain it to me ?? please!

Answer 3

almost the right idea, but I think you are going the wrong direction... what are the next three terms after 0? Should be getting larger, I think...

Answer 4

-30 ---> -14 increases by 16
-14 ---> -6 increases by 8
and so on...

Answer 5

Almost.. but you broke the pattern :)

to get from -6 to -2, increase by 4
to get from -2 to 0, increase by 2 (half as much as last increase)
So...
to get from 0 to the next term, increase by ___ to get ____

Answer 6

Ok, so.. I got that one...do ya'll know the answer to this one.....-4x+16/x2-9 ?

Answer 7

I think @haleym96 is still working through it... why don't you post this as a new question?

Answer 8

@JakeV8 So the next term is 1?

Answer 9

yeah, you're getting it now :)

How about the next two terms?

Answer 10

.5 and .25

Answer 11

well... those sound like the amounts of the increases, right? not the actual terms in the sequence?

The term you just found was "1".

So the next increase from 1 gives you the second term.

Answer 12

So, 1.5 and 1.25.

Answer 13

hehe... so so close...

Remember, it's increasing every time.

So the last term given was 0, and you increased correctly by 1 to get 1.

Then you increased again correctly by 0.5 to get 1.5

Finally, you increase FROM 1.5 by 0.25 to get ??

:)

Answer 14

Haha yeah, I got it now.

Answer 15

Good for you... just have to concentrate and not lose focus as you work through the pattern.

Was this homework for you too, or just something you were watching because it was interesting?

Answer 16

Just something I was trying to figure out myself.

Answer 17

I'm doing my homework, watching tv, and doing this so it got confusing haha.

Answer 18

@Greciamf so the next three terms are 1, 1.5, and 1.75

Answer 19

Awesome :) glad you stuck with it... nice to see... keep it up! :)

Answer 20

-30,-14,-6,-2,0?
-30&-14=16
-14&-6=8
-6&-2=4
-2&0=2
anwers:
0&1=1
1&1 1/2=1/2
1 1/2&1 3/4=1/4
bonus: 1 3/4&1 7/8=1/8

-30,-14,-6,-2,0,1,1 1/2,1 3/4,1 7/8
