Answer 4

@Spectrum

Answer 5

Haha I'm already here ..okay lets do the first one first shall we? ...from one term to the next what is happening..what i am saying is ..how do you get the next term each time? subtract 2 or add 6 or what?

Answer 6

it is going down 2?

Answer 7

correct if term 1 is -4 and you subtract 2 every time ..what do you think you need to do?

Answer 8

do it 100 times lol..but how would i do that in an easier way

Answer 9

-4 is term 1 so you need to add 2 btw...its not subtract ...99 times... so -4 + 2(99)

Answer 10

-4 and add 2 to that 99 times ...so -4 + 198 ...which is the same as 198 -4

Answer 11

i got 194

Answer 12

correct ^.^ so 194 is the 100 term

Answer 13

using the way i taught you ..do you think you could do the others? ..lets try the second one

Answer 14

ok!

Answer 15

Okay the second one is Find the 50th term of the sequence -5, -9, -13,....
-5 is the first term and you subtract 4 everytime ..so what do you think you need to do?

Answer 16

4(49)?

Answer 17

4(49) is the amount you would be dealing with and you need to subtract it from -5 :)

Answer 18

191?

Answer 19

mhmm :)

Answer 20

ok so for the third one..the numbers arent constant

Answer 21

you are multiplying by negative 2

Answer 22

-1 x -2 = 2 x -2 = -4 x -2 = 8 ...

Answer 23

so how would i incorporate 5o in that?

Answer 24

tbh if you had a calculator i would just multiply by -2 23 times since its not so many

Answer 25

oh yes! i meant 23 not 50..sorry

Answer 26

-46?

Answer 27

no it is much much more ....the best way to do this is -2^22

Answer 28

-4194304 ?

Answer 29

mhmmm

Answer 30

ok, so what about the last one?

Answer 31

1/5(10)?

Answer 32

no ....its divided by 4 10 times

Answer 33

-1/5 /4 = -1/20 /4 = -1/80 and so on ...10 times

Answer 34

ok..is there an easier way to find the 10 term for all of that? @Spectrum

Answer 35

to find the 10 sequence..do i have to do it 10 times

Answer 36

yeah ...just put -1/5 and then divide by 4 hit enter ...then dont press anything else but divide by 4 ..then you shouldbe at the 3rd term just hit enter 7 more times

Answer 37

there is a way to do it -1/5(1/4)^10

Answer 38

1.907?

Answer 39

no thats -1.907 x 10^-7 which is scientific way to write it .....
properly it would be 0.0000001907 normally ..okay?

Answer 40

-0.0000001907*

Answer 41

thanks!

Answer 42
