Question

Generate the first 5 terms of this sequence: (1 point)
f(1) = 1 and f(2) = 2, f(n) = f(n - 1) + f(n - 2), for n > 2.


1, 2, 3, 4, 5
1, 2, 3, 5, 7
1, 2, 3, 5, 8
1, 3, 5, 7, 9

Answer 1

HI!!

Answer 2

Hi, Please help I'm stuck..

Answer 3

you know \(f(1)\) adn \(f(2)\) right?

Answer 4

what \(f(n) = f(n - 1) + f(n - 2), \) means is that the next number is what you get when you add up the last two

Answer 5

so for example \(f(3)=f(2)+f(1)\)

Answer 6

you got that?

Answer 7

starts with \(1,2\) then the next one is \(1+2=3\)

Answer 8

Wait what??

Answer 9

@misty1212 I dont understand how to do more?

Answer 10

add the previous two to get the next one

Answer 11

To get any or just the next one?

Answer 12

\[1,2,\overbrace{3}^{1+2}\]

Answer 13

so then 2+3 ?

Answer 14

so we are at \(1,2,3\) next will be yes that

Answer 15

1,2,3,5,8?

Answer 16

@misty1212 right?

Answer 17

yes

Answer 18

sure

Answer 19

For the function f(x) = x + 7, what is the ordered pair for the point on the graph when x = 2b? (1 point)

(2b, 2b + 7)
(2b, x + 7)
(x, x + 7)
(x, 2b + 7)

Answer 20

if \(x=2b\) then in the first slot for \((x,y)\) you need to see \(2b\)

Answer 21

so 2b + 2b?

Answer 22

?

Answer 23

2b + y?

Answer 24

\[f(x)=x+7\\
f(2b)=2b+7\]

Answer 25

What?..

Answer 26

lol i guess you are confused, lets go slow

Answer 27

you have a function \(f(x)=x+7\) which means, take your number, whatever \(x\) is, and add \(7\) to it

Answer 28

2b + 7?

Answer 29

so for example \[f(3)=3+7=10\\
f(0)=0+7=7\\
f(-7)=-7+7=0\\
f(\pi)=\pi+7\\
f(\heartsuit)=\heartsuit+7\] and so on

Answer 30

yes so \[f(2b)=2b+7\] is the second coordinate

Answer 31

what would be the first?

Answer 32

yes, a very very rare A

Answer 33

A?

Answer 34

yup

Answer 35

OKay, i just have one more can you help me on this last one?

Answer 36

lol sure
