Question

Which sequence is modeled by the graph below?

coordinate plane showing the points 1, 1; 2, 2; 3, 4; and 4, 8

an = 1(2)n − 1
an = 2(1)n − 1
an = 1 + (2)n − 1
an = (2)(n − 1)

Answer 2

@Jhannybean plz help

Answer 3

i would choose #4, if I understand the notation correctly. An is equal 2 to the power of (n-1)

Answer 4

i agree ,
if

a(n) = 2^(n-1)

Answer 5

thank you very much :) @perl @Sergii

Answer 6

@perl i'm confused @sergii said that it was #4 and u said that its 2^(n-1) and thats 1 and 2

Answer 7

can you upload the original question, its a bit difficult to read

Answer 8

Which sequence is modeled by the graph below?

coordinate plane showing the points 1, 1; 2, 2; 3, 4; and 4, 8

an = 1(2)n − 1
an = 2(1)n − 1
an = 1 + (2)n − 1
an = (2)(n − 1)

Answer 9

your choices are difficult to understand

Answer 10

can you take a screen shot of it

Answer 11

@perl

Answer 12

ok then we want this function
a(n)= 1*2^(n-1)

Answer 13

so it would be A right?

Answer 14

the choices are :
a) an = 1*2^(n-1)
b) an = 2*1^(n-1)
c) an = 1 + 2^(n-1)
d) an = (2)*(n-1)

Answer 15

yes that is what I get

Answer 16

\(\Large 1, 1;~~ 2, 2;~~ 3, 4;~~ 4, 8\\~\\
\implies \Large 1, 2^{1-1};~~ 2, 2^{2-1};~~ 3, 2^{3-1};~~ 4, 2^{4-1|}\\~\\\)
